◆ Foundations

Pattern prep & toile

Gowns: All gowns · Fabric: Muslin/calico matched to fashion-fabric weight

0/5

True every seam: walk stitching lines and match notches before cutting anything.
Trace onto Swedish tracing paper; add 2.5 cm (1") fitting seam allowances on side seams and CB.
Mark grainline full-length, balance points, and the waistline on every piece.
Sew a toile with long machine basting; fit in the actual shoes and undergarments.
Transfer every fitting change back to paper, then re-true the seams.

◆ Foundations

Cutting with precision

Gowns: All gowns · Fabric: Silk, crêpe, velvet need single-layer cutting

0/5

Pre-treat fabric exactly as the finished gown will be cleaned.
Square the grain: pull a thread or tear crosswise, then block the fabric straight.
Cut single layer, right side up, flipping pieces for pairs; use a with-nap layout for velvet & satin.
Use weights, not pins, on silks; cut with long smooth shear strokes or a fresh rotary blade.
Thread-trace stitching lines in silk thread — they survive pressing and show on both sides.

◆ Foundations

Staystitching & stabilising

Gowns: Wrap tea, swing, circle, empire · Fabric: Bias-prone crêpe and chiffon

0/4

Staystitch curved and bias edges within 15 minutes of cutting — necklines, armholes, waist.
Stitch 3 mm inside the seamline, directionally: shoulder to centre, hem to waist.
On the wrap tea's V-neck, fuse 6 mm silk-organza or stay tape along the bias edge to stop gaping.
Hang circle and full skirts on a form for 24–48 h before hemming so the bias can drop.

◆◆ Intermediate

Underlining & interfacing

Gowns: Formal, wedding, Victorian, mermaid · Fabric: Silk organza, cotton batiste, cotton flannel (for satin)

0/4

Choose underlining for body, opacity or support: organza for crisp, batiste for soft, flannel under duchesse to hide seam shadows.
Cut underlining from the same pattern; hand-baste to the fashion fabric on a flat table, slightly rolled ('turn of cloth').
Treat the two layers as one from here on.
Use sew-in interfacing on silk; reserve fusibles for cotton and test on a scrap first.

◆◆ Intermediate

Seam finishes

Gowns: All gowns · Fabric: Match finish to fabric

0/5

French seam — sheer chiffon & georgette (swing, empire overlays).
Hong Kong finish — unlined crêpe, wool, heavier cottons.
Hand overcast with silk thread — couture standard for underlined silk.
Flat-fell — pioneer & day dresses in sturdy cotton.
Press every seam flat as sewn, then open, before crossing it with another seam.

◆◆ Intermediate

Hems

Gowns: Circle, swing, ball, mermaid, wedding · Fabric: Fabric-specific

0/5

Level the hem on the wearer with a hem marker, in the actual shoes.
Circle skirts: 6 mm rolled hem or horsehair braid for buoyancy.
Formal & wedding: 5–8 cm catch-stitched blind hem, stitched only to the underlining.
Mermaid: face the flare with a shaped facing so the curve can't ripple.
Chiffon: hand-rolled hem, ~10 stitches per inch.

◆◆◆ Advanced

Sleeves

Gowns: Puff, bishop, cap, Victorian leg-o'-mutton · Fabric: Silk taffeta, crêpe, organza

0/5

Ease stitch the cap between notches with two rows of long stitches; ease, don't gather (unless puff).
Shrink out cap ease with steam over a tailor's ham before setting.
Baste in from the sleeve side, check hang on the form, then machine-stitch.
Puff sleeves: support with an organza or tulle sleeve head so they don't collapse.
Hand-fell the lining to the armhole.

Zippers & closures

Gowns: Formal, wedding, mermaid, Victorian · Fabric: Invisible & hand-picked

0/5

Interface the zip seam allowances with a 2 cm strip of organza.
Couture: hand-pick a lapped zip with tiny prick stitches — invisible and kind to silk.
Wedding: 20–40 covered buttons with rouleau loops; set loops on a stay strip.
Victorian: hooks & bars, or spiral-bone lacing with a modesty panel.
Add a waist stay (grosgrain ribbon) so the zip never carries the strain.

◆◆◆ Advanced

Pressing like an atelier

Gowns: All gowns · Fabric: Velvet & satin are different beasts

0/5

Press as you sew — never sew across an unpressed seam.
Use a silk organza press cloth; test heat on scraps.
Velvet: press over a needle board or a spare velvet scrap, face down, steam held above.
Shape with ham, seam roll, point presser and clapper; let pieces cool on the board.
Satin: low heat, no steam on the face — watermarks are permanent.

◆◆◆◆ Master

Fitting notes & corsetry

Gowns: Formal, wedding, mermaid, Victorian · Fabric: Coutil, spiral steel bones

0/5

Three fittings: toile, basted fashion fabric, final hem.
Fit from the top down: shoulders → bust → waist → hips → hem.
Mermaid knee point sits 2–5 cm above the knee for walking.
Internal corselet: coutil with spiral steel boning at seams and CF/CB; tack to underlining.
Check sitting, walking, arms raised; leave 2–3 cm wearing ease at the bust for non-corseted gowns.
