Chiffon slides, georgette stretches, organza frays, velvet creeps and satin shows every pin hole. None of them is hard once you know the tricks. This lesson is the practical guide: how to cut, mark, stitch, seam and press each one.

What you’ll learn

  • How to cut slippery fabric straight.
  • Needles, threads and stitch lengths for each fabric.
  • Seams that look good on sheer cloth.
  • How to press without shine, marks or flattened pile.

Before you start

  • Difficulty: intermediate. Make one cotton garment first.
  • Time: allow about half as long again as for cotton.
  • Kit: new fine needles (60–70 for sheers, 70–80 for crepe and satin, 80–90 for velvet), fine glass-head or silk pins, sharp shears or a rotary cutter, tissue or pattern paper, a pressing cloth, a velvet board or thick towel.

Cutting slippery fabric, step by step

  1. Cover the table with a cotton sheet or paper. Fabric grips cloth better than a smooth table.
  2. Find the grain. Pull a weft thread and cut along the line, or line the selvedge up with the table edge.
  3. Cut single layer, flipping the pattern for the second piece. Folded chiffon shifts.
  4. Sandwich if needed. Lay fabric on paper, pin pattern on top, and cut through all layers.
  5. Pin within the seam allowance only; or use weights instead of pins on satin.
  6. Mark with tailor’s tacks or thread, not chalk that won’t brush off.

Stitching

  • Shorter stitch (about 2 mm) on sheers; normal on velvet.
  • Polyester or fine silk thread.
  • Start on tissue so the machine doesn’t swallow the edge.
  • Hold the thread tails as you start.
  • Use a straight-stitch plate or a single-hole foot if you have one.
  • Walking foot for velvet and crepe; it stops layers creeping.

Seams and hems

  • French seam for chiffon, georgette and organza: neat inside and invisible from outside.
  • Rolled hem (by hand or with a rolled-hem foot) or pico on dupattas and saree edges.
  • Overlock velvet edges; it frays and sheds.
  • Bias binding in self-fabric or organza for sheer necklines.

The one habit that matters most: sew a test seam on a scrap of the same fabric, with the same layers, every time. Adjust needle, stitch length and tension on the scrap, never on the garment.

Fabric by fabric
Fabric Main problem Main fix
Chiffon Slides, frays Cut on paper, French seams, rolled hems
Georgette Stretches on the bias Stay-stitch, hang 24 hours before hemming
Crepe Shrinks with steam, ripples Pre-steam, walking foot
Organza Frays, shows seams French seams, narrow hems
Satin Pin holes, snags, slips Pins in seam allowance, new needle, weights
Velvet Creeps, pile crushes Hand-baste, walking foot, steam not press
Net Catches, melts Tissue under, low heat
Tips, tricks and hacks
  • Spray starch chiffon before cutting, then wash it out; it behaves like cotton for a while.
  • Tape the edge: a strip of paper tape along a sheer edge holds it steady for stitching; tear it away after.
  • Hang bias garments overnight before hemming; the hem drops.
  • Use a pressing cloth of silk organza; you can see through it.
  • Press velvet face down on a towel or a spare piece of velvet.
  • Baste velvet seams by hand, then machine.
  • Cut velvet with the pile running down for a lighter shade, up for richer colour – but all pieces the same way.
  • Sew satin with a new needle every garment.
  • Pre-shrink crepe by steaming the whole length.
  • Keep hands smooth; rough skin snags satin and chiffon.
Problems and how to fix them

The fabric gets pulled into the machine

  1. Start on a tissue strip.
  2. Use a smaller needle and a single-hole plate.
  3. Prevention: always start sheers with tails held and tissue under.

Seams pucker

  1. Lengthen the stitch slightly and loosen top tension.
  2. Hold the fabric gently taut (not stretched) in front and behind the foot.
  3. Prevention: test on a scrap first, with the same layers.

The pieces are off grain after cutting

  1. Recut if you have fabric.
  2. Stay-stitch and ease to the pattern before sewing.
  3. Prevention: cut single layer on paper.

The hem is uneven after a day

  1. Hang it again and re-mark from the floor.
  2. Trim and re-hem.
  3. Prevention: hang bias and georgette 24 hours before hemming.

Velvet layers have crept

  1. Unpick and hand-baste.
  2. Use a walking foot, stitching in the direction of the pile.
  3. Prevention: baste every velvet seam.

Shiny marks after pressing

  1. Steam lightly from the back; some shine lifts.
  2. Brush the area gently.
  3. Prevention: always use a pressing cloth and a lower setting.

Pin holes show on satin

  1. Steam gently; small holes may close.
  2. Move the seam if possible.
  3. Prevention: pin only in the seam allowance, or use weights and clips.
Beginner mistakes and myths
  • Cutting folded chiffon to save time.
  • Using an old needle (“it still sews”).
  • Pressing velvet like cotton.
  • Myth: “Sheer fabrics need very tight tension.” They need balanced, slightly looser tension.
Practice drills
  1. Beginner: sew three French seams on chiffon scraps.
  2. Intermediate: roll-hem a 1-metre chiffon dupatta edge by hand.
  3. Advanced: make a lined velvet clutch with matched pile.
As a hobby, for earning, for teaching

As a hobby: start with a chiffon scarf; it teaches cutting and rolled hems in an afternoon.

For earning: neat French seams and invisible hems on party wear are what separate a professional finish from a home one.

For teaching: demonstrate cutting on paper live; learners rarely believe it works until they see it.

Check yourself
  • Can you cut chiffon straight on a single layer?
  • Can you sew a French seam?
  • Do you know why bias garments hang before hemming?
  • Can you press velvet without crushing it?
Key terms
  • French seam: a seam enclosed within itself.
  • Rolled hem / pico: narrow finished edges.
  • Walking foot: a foot that feeds both layers evenly.
  • Tailor’s tack: a thread mark.
Variations: hand sewing, left-handed and no special feet
  • By hand: a small running stitch with a back stitch every few stitches works beautifully on chiffon and georgette; hand rolled hems are the finest finish of all.
  • Left-handed: for hand-rolled hems, roll the edge towards you and work from left to right; for the machine, nothing changes.
  • No walking foot: hand-baste velvet and crepe seams, and stitch slowly with lighter presser-foot pressure.
  • No rolled-hem foot: stitch 5 mm from the edge, fold on the stitching, stitch again, trim close, fold once more and stitch.
Planning the order of work
  1. Pre-treat (steam or wash) and rest the fabric flat overnight.
  2. Cut single layer on paper, all pieces in one session.
  3. Stay-stitch necks and bias edges at once.
  4. Fuse or sew interfacing before any construction.
  5. Sew test seams on scraps of the same layers.
  6. Construct, pressing each seam as you go with a cloth.
  7. Hang overnight, then hem.
Control: tension, pressure and speed
  • Tension: start balanced; loosen the top slightly if seams pucker.
  • Pressure: lighten the presser foot for velvet and crepe, if your machine allows.
  • Speed: slow and steady; fast sewing pulls sheers out of line.
  • Hands: guide, don’t pull; one hand in front of the foot, one behind.
Care and finishing
  • Chiffon, georgette: cold hand wash or dry-clean; dry flat; press low with a cloth.
  • Organza: press on low; steam can soften silk organza’s crispness.
  • Satin: press on the reverse only.
  • Velvet: steam from the back; hang on padded hangers; dry-clean if heavily embroidered.
  • Net: never hot; store loosely so it doesn’t crush.
Sequins, embroidered net and heavy embellishment
  1. Mark seam lines with thread on the right side.
  2. Remove sequins or beads from the seam allowance by cutting the threads (not the fabric); keep them to replace later.
  3. Secure loose ends next to the seam with a dab of fray stopper or a few hand stitches.
  4. Stitch with a zipper foot or a heavy-duty needle, slowly.
  5. Hand-sew the removed sequins back over the seam so it disappears.
  6. Line fully so nothing scratches the skin.

Never press sequins on the face; many are plastic and melt.

  • Hems even when hung, measured from the floor.
  • No pin holes on satin; no crushed pile on velvet.
  • Linings sitting smoothly, not peeping at the hem.
  • Loose threads trimmed, inside and out.
Sources and uncertain points
  • General tailoring practice; needle sizes are typical, not fixed. Teacher to check against D&D’s own studio method.
