Quick fix: Rip out the bind-off, place live stitches back on the needle, and re-bind off using a needle 2–3 sizes larger. A larger needle gives the edge the slack it needs to lie flat.
What you are seeing
The bound-off edge of your piece is rolling inward, puckering, or pulling tight — the edge waves or cups instead of lying flat, and the piece looks distorted. The bind-off is too tight relative to the fabric tension.
Why it happens
- Binding off with the same needle size as the body — the bind-off naturally pulls tighter than stockinette
- Pulling the yarn too tightly between each bound-off stitch
- Using a standard bind-off where a stretchy one was needed (necklines, cuffs, lace edges)
Fix it now
- Identify the type of edge: neckline (needs stretch), hem (needs stability), or lace (needs drape).
- Rip out the bind-off by snipping the chain at the center of the edge and carefully pulling both ends — the bind-off unravels cleanly. Collect all live stitches on a needle.
- For a standard flat edge: bind off again using a needle 2–3 sizes larger. Keep your grip loose between each stitch.
- For necklines and cuffs: use a stretchy bind-off method. See How to do a stretchy bind off.
- Test by stretching the edge gently — it should relax back without pulling.
Prevent it next time
- Always bind off one to three needle sizes larger than your working needle
- Bind off loosely — consciously pull out extra yarn with each stitch
- Choose your bind-off method by edge type: stretchy for openings, firm for hems, elastic for lace
