I have taught 2,000+ students in 24 years. Five mistakes come up in every batch. Here is how to avoid them.
Mistake 1: Wrong needle for the fabric
A heavy denim needle on chiffon will tear it. A fine needle on canvas will bend or break.
The rule: lightweight fabric → lightweight needle (60/8 or 70/10). Medium → 80/12 or 90/14. Heavy → 100/16 or 110/18. Most home machines come with an 80/12 — fine for cottons, wrong for silk or denim.
Mistake 2: Wrong thread tension
Loose loops on one side, bunched stitches on the other. The fix is small adjustments to the upper tension dial. Always test on a scrap before your real fabric. Spend two minutes here and save two hours later.
Mistake 3: Not pre-washing fabric
You stitch a beautiful kurta. First wash, it shrinks 10%. Now it does not fit.
Always pre-wash and iron cotton fabrics before cutting. Cotton shrinks. Silk does not usually. Synthetics never. Treat your fabric the way the finished garment will be treated.
Mistake 4: Cutting without marking
Eyeballing seam allowances. The result: uneven hems, mismatched seams, frustration.
Take 5 extra minutes. Use chalk or tailor’s pencil. Mark every dart, every seam, every notch. Cutting accurately is 70% of clean stitching.
Mistake 5: Skipping the press
A pressed seam looks crisp. An un-pressed seam looks home-made.
Iron between major construction steps, not just at the end. Each seam, each dart, each hem. The iron is the second-most important tool after the machine.
One bonus mistake
Not pressing onwards through frustration. Every student hits a wall around week 3-4 of a course. The garment is not coming together. You are tired. You think it is not for you.
It is. Push through. Week 5 is when it clicks.
