Taking accurate body measurements

Measure over close-fitting clothing with a flexible, non-stretch tape and, whenever possible, a trained partner. Establish the natural waist with narrow elastic and mark key landmarks such as the shoulder point, bust point, full hip and wrist. Keep girth measurements level and the tape comfortably snug without compressing the body. Record the unit, date, body side and exact method; repeat critical measurements and resolve differences before drafting. Measure the body itself—not a favourite garment—and keep ease outside the measurement record.

Practice: Create a dated measurement chart, take every critical dimension twice, and remeasure any result that differs by more than your studio tolerance.

Understanding body proportions

Proportion describes how lengths, widths and circumferences relate, while posture describes how those dimensions are carried. Two people with the same bust, waist and hip girths may need different shoulder slopes, back lengths, dart positions, rises or front-to-back distribution. Compare vertical levels—shoulder to bust, waist to hip, waist to knee—and divide girths into meaningful front and back measurements rather than assuming symmetry. Use observations to choose a starting block and locate fitting lines, never to label one body as the universal norm.

Practice: Draw a front and side body map with horizontal balance levels, then annotate where your measured proportions differ from the selected base chart.

Standard sizing systems (EU, US, UK)

EU, US and UK size labels are identifiers used within particular standards, brands and product categories; they are not dependable one-to-one conversions. The same label can represent different body dimensions, ease policies or target customers, and womenswear, menswear and childrenswear use different primary measurements. ISO 8559-2 promotes size designation through stated body dimensions rather than garment dimensions. For pattern work, identify the exact chart or standard, its intended population, garment category and base size before using any label.

Practice: Compare three current brand charts that use different regional labels and map their stated body measurements, not the printed sizes.

Size charts

A size chart translates a target population into coordinated body measurements and size intervals. Distinguish a body-measurement chart from a finished-garment specification: the latter already includes wearing and design ease. Select the size from the measurement most critical to the garment, then plan alterations for the other dimensions. Check whether the chart uses full-bust or high-bust selection, natural or lowered waist, actual body height and any cup, fit or age category. Never mix drafting formulas and measurements from unrelated charts without recalibrating the block.

Practice: Add columns for body, selected size, finished garment and required alteration so the source of every dimension remains visible.

Ease allowance (wearing ease & design ease)

Wearing ease provides room for breathing, sitting and movement; design ease creates the intended silhouette beyond that functional minimum. Total ease is the difference between the relevant body dimension and the finished garment at the same level. It varies with garment layer, fabric weight, stretch, cut and activity. Stretch garments may use negative ease, but only after testing stretch percentage, recovery and direction. Allocate ease deliberately around the body rather than adding it evenly by habit, and validate the result in the intended fabric or a comparable toile.

Practice: Prepare close, semi-fitted and loose specifications from one body chart, then explain how each ease distribution supports movement and style.

Basic bodice block

Establish centre front, centre back, bust or chest, waist and armhole-depth lines on square reference axes. Plot neckline, shoulder, armscye, side seam and dart shaping from the measurement set required by the chosen system. The front and back must share compatible shoulder and side-seam stitch lengths while retaining their different contours. Close darts temporarily when trueing adjacent edges, label bust point separately from dart point, and keep the master free of decorative styling. A stable woven toile confirms balance, ease and anatomical placement.

Practice: Fit one toile and check level bust and waist lines, shoulder placement, vertical side seams and clean armholes before approving the master.

Basic skirt block

Draft from waist, full hip, waist-to-hip depth and skirt length, adding only the ease specified for the block. Distribute the waist-to-hip difference between side-seam shaping and front or back darts so no single area carries inappropriate suppression. Shape the waist with darts folded, blend the hip curve and walk the side seams along their stitch lines. A balanced skirt has correctly placed waist and hip levels, straight centres, vertical side seams and a level hem in the toile.

Practice: Mark horizontal balance lines on the toile and transfer each fitting correction back to paper before re-trueing waist, hip and side seams.

Basic pants/trouser block

Trousers require waist, hip, rise or crotch depth, crotch length, thigh, knee, hem and vertical lengths. Build the draft around a stable grainline and shared waist, hip, crotch, knee and hem levels. Front and back crotch extensions and curves are deliberately different because they accommodate different body volume. Keep the leg balanced around the grainline, walk inseams and outseams, and inspect whether the crotch seam follows the body without pulling, collapsing or restricting movement. Correct depth before attempting to correct length.

Practice: Fit a toile with waist, hip, knee and grain lines marked, then assess it while standing, sitting and walking.

Sleeve block

Draft the sleeve only after the bodice armhole is corrected. Use the armhole information required by the system together with sleeve length, upper-arm and wrist measurements. Establish grainline, cap height, biceps, elbow and hem levels; retain distinct front and back cap shapes. Walk the sleeve-cap stitch line against the armhole, position underarm and shoulder balance marks, and record any intentional cap ease. Test hang and mobility: the sleeve grain should follow the arm, and the cap should set without unintended tucks.

Practice: Insert the trial sleeve into the bodice toile and diagnose whether any twist belongs to sleeve pitch, armhole balance or both.

Shirt block

A shirt block develops the bodice for a looser, construction-led garment. Add the planned ease, length and front overlap, then define shoulder or back yoke, neckline, armhole and hem. Coordinate the body with a lower-cap shirt sleeve, cuff and placket; the sleeve may have little or no cap ease depending on the system. Plan collar and stand from the completed neckline stitch line, not an early draft. Centre-back pleats or gathers can add movement without shifting the shoulder fit.

Practice: Make a half-scale shirt set and verify yoke, armhole, sleeve, cuff, placket, collar and stand as one connected system.

Princess seams

A princess seam converts dart shaping into a continuous style line, usually running from shoulder or armhole through the bust area to the waist and beyond. Rotate the block’s dart intake into the chosen line, separate the panels and smooth the curves without removing the required volume. Place the seam near the bust point but shape the sewn line to finish away from it. Walk the matching stitch lines, distribute any controlled ease, add balance notches and check that the seam remains visually smooth in the toile.

Practice: Develop shoulder and armhole versions from the same bodice block, then compare their panel shapes and fitting control.

Empire waist

An empire seam sits below the bust and separates the upper bodice from the lower garment. Establish its position on a fitted toile or accurately mapped block, keeping it level or deliberately shaped as the design requires. Transfer bust shaping into the upper section, then true the lower edge with darts or princess seams closed. Walk the upper and lower stitch lines and add enough balance points to control a strongly curved seam. Consider closure placement, support, seam bulk and the behaviour of the selected fabric.

Practice: Mark the seam on a toile, transfer it to paper and test whether it remains correctly positioned during breathing and arm movement.

Yokes

A yoke is a fitted upper or lower panel that can provide structure while supporting gathers, pleats or fullness in the adjoining section. Draw the yoke line on a tested block, transfer or absorb any intersected dart intake, then separate the pieces. Close absorbed darts before trueing the yoke edge; open planned fullness only in the adjoining panel. Walk the seam, mark centres and balance points, and consider whether the yoke is single, faced, doubled or cut on a different grain.

Practice: Convert a back shoulder dart into a shirt yoke and add a controlled centre-back pleat below it.

Dart manipulation

Dart manipulation relocates or redistributes shaping without changing the block’s total intake. Mark the shaping pivot, choose a new direction and close the original dart so an equivalent opening appears elsewhere. One dart can become two smaller darts, a seam, tuck, pleat or controlled gathers, provided the three-dimensional volume is retained. The final dart point normally stops before the body prominence; its exact distance depends on size, garment, fabric and fit. Recheck grainline and affected edges after every change.

Practice: Create four half-scale variations from one bodice and label where the original intake has moved in each design.

Dart rotation

Dart rotation is the controlled movement of a dart around its pivot. On a bodice, a waist dart may rotate to the side seam, shoulder, neckline, centre front or armhole while preserving fit. Extend both original and proposed dart lines to the pivot, then use pivoting or slash-and-spread to close one opening and create the other. Redraw the working dart from the new seam to its final point, true the edge with the dart folded, and avoid placing bulky intake where construction or fabric makes it impractical.

Practice: Rotate the same dart to three positions and overlay the patterns to confirm that the outer fit remains consistent.

Dart elimination

Eliminating a visible dart does not mean discarding its shaping. The intake must be absorbed into a style seam, transferred to another dart, released as gathers or pleats, eased into a seam, or genuinely removed because the design, fabric stretch or desired fit no longer requires it. Simply closing a dart without opening or reallocating volume changes the pattern’s perimeter and balance. Decide the destination of the shaping first, then walk and fit the altered pattern.

Practice: Hide one bodice dart in a princess line and a second in neckline gathers, documenting the shaping destination on each pattern.

Slash and spread technique

Slash-and-spread adds, removes or transfers volume through controlled cut lines. Mark the hinge or pivot, cut to—but not through—it, then open or overlap the sections by measured amounts. Keep a stable reference such as grainline, seam or hem level, secure the pattern on new paper and blend the resulting edges. Parallel spreading adds even fullness; radiating spreads add flare around a pivot. Record every opening so paired or symmetrical pieces can be reproduced accurately.

Practice: Use parallel spreads for gathers and radiating spreads for flare, then compare the changed perimeter and grain direction.

Pivot method

The pivot method transfers a dart without cutting the master. Place the block on paper, mark the pivot and both dart legs, and trace from the new dart position around the pattern to one original dart leg. Hold the pivot securely, rotate the block until the original dart closes, then continue tracing to the new position. The untraced opening becomes the new dart. Pivoting is efficient for repeated exercises, but accuracy depends on preventing the pivot from drifting and restoring every reference mark.

Practice: Repeat one rotation using pivot and slash-and-spread, then compare the two copies by overlaying their stitch lines.

A-line skirts

An A-line skirt stays controlled at the waist and hip, then widens toward the hem. Start from a tested skirt block and transfer part or all of the waist-dart intake into hem flare by cutting to the dart apex and closing the dart. Distribute flare across more than one line when a smoother silhouette is required, while keeping centre front and centre back straight unless seams are planned. Blend the waist and hem, preserve grainlines and compare the new side-seam angles before adding allowances.

Practice: Draft two flare amounts from one block and hang both half-scale samples to compare silhouette and balance.

Pencil skirts

A pencil skirt follows the body through the hip and narrows toward the hem. Begin with a fitted skirt block, establish the finished length and taper the side seams gradually below the full-hip level. Excessive taper restricts stride, so plan a back, side or front vent, slit or pleat that restores movement. Keep the grainline stable, walk the tapered seams and true the vent extensions in their folded position. Fabric stretch and lining can materially change the required ease.

Practice: Calculate the finished hem circumference, compare it with a comfortable walking requirement and size the vent before cutting the toile.

Gathered skirts

A gathered skirt contains a longer edge that is drawn into a shorter waist, yoke or waistband seam. Decide the finished waist and distribute extra width according to the fabric, desired density and placement; a crisp fabric and a fluid fabric do not produce the same result at one fixed ratio. Mark centres, side seams and distribution points so fullness remains controlled. Consider bulk at closures and waist seams, and keep the grainline appropriate for each panel.

Practice: Sew equal-length samples at three fullness ratios in the intended fabric and select by appearance, bulk and recovery rather than formula alone.

Pleated skirts

Pleats add planned volume through folds with defined placement and intake. Specify the finished visible width, fold direction, underlay and total intake for each knife, box or inverted pleat. The pattern must show placement lines, fold lines and match points clearly; repeated pleats also need a verified interval so the final panel reaches the required waist. Decide whether pleats are stitched down, pressed, released or supported by interfacing, and account for turn-of-cloth in bulky fabrics.

Practice: Draft one knife-pleat repeat and one box-pleat repeat, fold them in paper, and verify both the finished width and total fabric consumption.

Circle skirts

A circle skirt creates flare by cutting the waist as an inner arc and the hem as a larger concentric arc. For a full circle, the theoretical waist radius begins with circumference divided by 2π; half- and quarter-circle drafts use different geometry. The final radius must also account for seam configuration, waistband treatment, stretch and the behaviour of the waist edge. Much of the hem falls on bias, so stabilise the waist, allow the garment to hang and level the hem before finishing.

Practice: Draft quarter-, half- and full-circle miniatures from the same waist measurement and compare hem sweep, fabric use and grain distribution.

Blouses

Develop a blouse from a bodice or shirt foundation according to the intended fit. Establish length, ease, neckline, closure and hem first, then translate darts into seams, gathers, tucks or a looser silhouette. Coordinate armhole and sleeve, plan facings or bindings, and check that buttons, plackets and collars share the same centre-front and neckline logic. Lightweight or sheer fabrics may require wider curves, reduced bulk, stabilisation or a different finishing method than the toile.

Practice: Convert one bodice into a blouse with a yoke and gathered lower section, then prepare a complete pattern-piece and construction checklist.

Dresses

A dress coordinates bodice, waist or torso and skirt as one balanced garment. Decide whether the silhouette is fitted, semi-fitted or loose and whether a waist seam, princess seam or continuous panel carries the shaping. Match corresponding waist stitch lines after all darts, pleats or gathers are accounted for. Check closure access, walking and sitting ease, lining, support, hem balance and the effect of fabric weight across the full length. Long vertical seams magnify small errors, so walk and notch them carefully.

Practice: Combine a corrected bodice and skirt, mark shared balance lines, and test the complete dress toile rather than fitting its halves independently.

Simple jackets

A jacket block needs room for the intended underlayer plus structural and design ease. Develop front overlap, neckline or lapel, shoulder, armhole, sleeve and hem as a connected system. Add facings, front support, pocket placement and lining patterns only after the shell lines are validated. The collar and lapel depend on the break and roll lines; the sleeve must suit the jacket armhole rather than an unrelated bodice. Account for fabric thickness and turn-of-cloth at edges and collars.

Practice: Create a simple single-breasted jacket toile, test it over the intended layer and review closure, reach, shoulder balance and sleeve pitch.

Set-in sleeve

A set-in sleeve joins a complete sleeve cap to the bodice armhole. Walk both stitch lines from underarm to shoulder, confirm front and back notches, and identify any intentional cap ease. Ease must be distributed in its designated zone without visible gathers unless the style calls for them. Sleeve pitch controls how the arm hangs, while cap height and biceps width influence appearance and mobility. Test the sleeve in the actual armhole, because altering either seam changes their relationship.

Practice: Mark the grain and biceps lines on a toile sleeve, insert it by balance marks and assess smoothness with the arm relaxed and moving.

Raglan sleeve

A raglan sleeve replaces part of the bodice shoulder and armhole with diagonal seams that run toward the neckline. Develop it from the bodice and sleeve together so the new seam preserves chest, back and shoulder volume. Decide whether the raglan line contains a shoulder dart, seam shaping or extra mobility, then smooth and walk the front and back joins separately. Curved diagonal seams need clear notches, and the neckline must be remeasured before drafting a collar.

Practice: Tape a bodice and sleeve copy at their relationship points, draw the raglan line, separate the new pieces and compare their shared seams.

Kimono sleeve

A kimono or cut-on sleeve extends from the bodice without a conventional armhole seam. Its shoulder angle, underarm depth and sleeve width determine both silhouette and reach. A deep underarm increases movement but changes the visual line; a closer underarm may require a gusset or additional shaping to prevent lifting and strain. Maintain clear grain references through the enlarged piece and test the design with arms raised and forward, not only in a static pose.

Practice: Draft two underarm depths from one bodice and compare mobility, fabric use and drag lines in half-scale or calico samples.

Puff sleeve

A puff sleeve adds controlled fullness at the cap, hem or both. Divide a basic sleeve into vertical sections, slash toward a stable hinge and spread the sections evenly or selectively to position volume. Redraw the cap and hem smoothly, then mark the gathering area and its receiving seam or band. More spread creates more volume but also more bulk; fabric body, weight and support strongly affect the result. Keep underarm seam lengths compatible and preserve sleeve pitch.

Practice: Test cap-only, hem-only and combined puff variations in one fabric, recording spread and finished appearance for each.

Bell sleeve

A bell sleeve stays relatively controlled through the cap and upper arm, then widens toward the hem. Use radiating slash-and-spread lines from the hem toward hinges near or above the cap, keeping the cap seam essentially unchanged unless the design also adds crown fullness. Blend the new hem, check whether the intended edge is level when worn and plan an appropriate finish for the increased circumference. Added flare shifts grain directions and can create uneven drop in fluid fabrics.

Practice: Draft moderate and dramatic bell spreads, hang the samples and level their hems after the fabric has relaxed.

Bishop sleeve

A bishop sleeve is comparatively smooth at the cap and full toward the wrist, where it is gathered into a cuff or band. Slash vertically and spread more strongly at the hem while controlling any addition at the cap. The sleeve length must include the soft overhang intended above the cuff, and the cuff must fit the wrist or hand opening with its closure. Mark gathering zones and placket position, and verify that the fullness distribution does not twist the sleeve.

Practice: Develop one bishop sleeve with a fitted cuff and test whether the chosen spread, length and fabric create the intended drape.

Cap sleeve

A cap sleeve provides short shoulder coverage and may be developed from the upper portion of a set-in sleeve or integrated with the bodice. Determine where it begins and ends in the armhole, then true those intersections so they join without points or gaps. Because coverage is brief, small changes in cap width and underarm position strongly affect movement and exposure. Plan the lower edge finish and test the sleeve with the arm lifted and forward.

Practice: Trace three cap depths on a toile and evaluate proportion, coverage and mobility before finalising the pattern.

Shirt collar

A classic shirt collar commonly uses a separate stand and fall. Measure the finished neckline between the exact attachment points, draft the stand to that seam and coordinate its centre front, button extension and upper edge with the collar. The collar’s outer edge and point shape determine its visual spread, while the stand controls how it rises around the neck. Add roll and turn-of-cloth appropriate to fabric and interfacing, and distinguish upper collar from undercollar when their patterns differ.

Practice: Assemble a stand-and-collar sample, then verify neckline length, front alignment, roll and point symmetry on the shirt toile.

Peter Pan collar

A Peter Pan collar is a flat or low-roll collar with a rounded outer edge. Trace the completed front and back necklines with shoulder seams aligned, then shape the outer edge to the desired width and curve. A collar that follows the neckline closely lies flatter; controlled overlap or spreading at the outer edge changes roll and flare. True centre back, shoulder and front ends, add balance marks, and account for the closure and facing beneath it.

Practice: Draft a close flat version and a slightly rolled version, then compare how their outer edges sit on a half-scale neckline.

Mandarin collar

A Mandarin collar is a narrow standing collar with clean front ends and usually no separate fall. Draft its lower edge from the completed neckline and shape the upper edge so it stands without collapsing or cutting into the neck. Decide whether the front meets edge to edge, overlaps or curves away, and coordinate that choice with the garment closure. Small changes to centre-front height, back height and curvature affect comfort and posture, so test it in the final fabric and interfacing.

Practice: Make two collar-stand samples with different top-edge shaping and assess neck clearance, front meeting and stability.

Stand collar

A stand collar is the broader category of collars that rise from the neckline; it may be straight, shaped, overlapping or used beneath another collar. Its lower seam must correspond to the neckline, while the amount of shaping between lower and upper edges determines how it follows the neck. Establish centre back, shoulder and centre-front references, then plan overlap, button placement and any facing or undercollar. Interface according to the required support without ignoring added thickness.

Practice: Develop one straight and one shaped stand from the same neckline, then compare fit and angle on the form.

Shawl collar

A shawl collar forms a continuous visual line from the front lapel around the back neck, often as a grown-on extension of the front or facing. Establish centre front, break point, roll line and neckline before constructing the collar extension. The back-neck seam must match the bodice, and the outer edge needs enough length and turn-of-cloth to roll without pulling. Create the facing from the completed front and collar shape, then mark roll, shoulder and centre-back balance points.

Practice: Fold the paper pattern along the roll line, then make a supported toile to evaluate lapel width, back-neck fit and roll.

Notched collar

A notched collar coordinates a front lapel with a separate upper collar at the gorge and notch. Draft the jacket front, break line and lapel first; then develop the collar so its neckline seam, stand and roll work with that geometry. The gorge seam, collar point, lapel point and notch must meet in their sewn positions, not merely on flat cut edges. Allow for undercollar shaping, seam roll and turn-of-cloth, and develop a facing that supports the entire front edge.

Practice: Sew a half-collar and lapel sample, clip and press the notch accurately, and assess symmetry with the jacket closed and open.

Patch pocket

A patch pocket is applied to the garment surface, making shape and placement highly visible. Draft the finished outline first, test it with a hand and the intended contents, then add top turning, seam allowances and any lining or interfacing. Shape templates help press curves consistently. Mark centre and placement references on both pocket and garment, and reinforce upper corners against repeated use. Stripes, checks, nap and print motifs may require deliberate matching or contrast.

Practice: Pin a paper pocket to the toile, test access and visual balance, then sew a fabric sample with reinforced upper corners.

Welt pocket

A welt pocket is built through a precisely marked opening with one or two narrow lips and a hidden pocket bag. Draft the finished opening, welt pieces, pocket bag and any flap together; include clear centre, end and stitching marks. Stabilise the garment area before cutting, sew an exact rectangle and clip only after the stitching is checked. Welt width must remain even, corners must turn cleanly and the bag must hang without showing or pulling.

Practice: Make at least two samples in the project fabric and interfacing before cutting the garment; record the exact opening and welt dimensions.

Side seam pocket

A side-seam pocket hides its opening within a structural seam. Establish an accessible opening position on the toile, then draft front and back pocket-bag pieces that join the seam and provide useful depth. Match opening notches on both garment panels, keep seam allowances compatible and anchor the bag at waist, yoke or another stable point when needed. The bag should fall toward the front or intended direction without distorting the side seam.

Practice: Insert a pocket into a skirt side seam, load it with a typical object and check seam hang, reach and bag visibility.

Cargo pocket

A cargo pocket is an external utility pocket whose capacity may come from a box pleat, bellows, gusset or expanded side panels. Begin with the required finished capacity and opening, then add expansion, top turning, flap, fastening and seam allowances. The placement must work with body movement and nearby seams, while the base fabric may need reinforcement under load. True folded corners in paper and mark every fold, placement line and match point.

Practice: Build a paper model first, then sew a loaded sample to evaluate expansion, flap coverage, corner accuracy and attachment strength.

Trueing seams

Trueing refines altered lines so they form smooth, sewable relationships. Blend curves without bumps or flat spots, fold darts, pleats and tucks into their sewn positions, and reshape the edge that crosses them. Square seam intersections when the assembled edge must continue cleanly, and true hems with vertical seams folded as they will be sewn. Work on stitch lines before allowances; otherwise the finished geometry can be hidden by unequal cut edges.

Practice: Audit every neckline, armhole, dart, panel seam and hem on a pattern set, marking each completed trueing check in a different colour.

Walking patterns

Walking compares adjoining stitch lines by placing them together at a starting point and rotating one pattern along the seam. Walk the actual sewing lines, not the outside cut edges, and exclude dart intake or pleat underlay according to the construction. Match endpoints and balance marks, then identify intended ease separately from accidental excess. Curved seams such as princess lines, collars and sleeve caps require short, controlled steps without stretching the paper.

Practice: Walk shoulders, side seams, sleeve cap, princess panels and collar neckline; record the amount and location of every mismatch before correcting it.

Adding seam allowance

Add seam allowance only after fit, style lines and stitch-line relationships are approved. Choose widths according to seam type, fabric stability, machinery, enclosed finish, curve and fitting needs; one universal width is rarely appropriate for every edge. Offset consistently from the stitch line, then true corners with adjoining seams, darts or hems folded into their sewn position. Label whether allowance is included, distinguish cut and stitch lines, and retain a clean master without hidden production changes.

Practice: Create an allowance specification for the whole garment, apply it to a traced pattern and inspect every intersecting corner before cutting.

Grainline placement

Grainline controls hang, stretch, stability and visual direction. Lengthwise grain is normally parallel to the selvage and is the usual foundation for vertical garment balance; cross grain and bias behave differently and should be chosen deliberately. Restore or redefine the grainline after every manipulation, keeping it long enough to measure at both ends. Also specify cut-on-fold, nap, one-way print, stripe or stretch direction where relevant, and verify altered panels as a coordinated set.

Practice: Lay each piece on fabric and measure both ends of its grainline to the same selvage; document any intentional off-grain or bias placement.

Notches

Notches divide seams into reliable construction checkpoints and distinguish front, back or adjoining pieces. Place them at centres, major balance positions, curve transitions, style-line joins, controlled-ease zones and the beginning or end of gathers or pleats. Every notch should have a precise purpose and matching partner; too many create confusion. Position them perpendicular to the seam and within the allowance, using the studio’s consistent single, double or triple convention without cutting into the stitch line.

Practice: Remove every decorative or redundant notch from one pattern set, then verify the remaining pairs by walking all adjoining seams.

Balance marks

Balance marks preserve the garment’s relationship to the body and help complex pieces assemble correctly. They include centre front and back, bust or chest, waist, hip, biceps, elbow and knee levels; shoulder, underarm and panel positions; pocket and button placements; dart points and drill marks. Use the safest mark for the fabric and construction method, keep labels unambiguous and transfer fitting changes to every affected piece. Horizontal balance lines should remain level in a well-balanced toile unless the design intentionally redirects them.

Practice: Complete a final pattern audit: piece name, size, cut quantity, material, grainline, centres, balance levels, notches, internal marks, allowance status and version date.
