Fix crochet curling, cupping and ruffling

Lay the work flat and locate the change: a tight starting edge, a bowl-shaped round or a wavy outer edge. Check counts before using blocking to force the shape.

US termsNeeds: Crochet in the round
Start here

Compare the problem round’s total with the pattern: a bowl points to missing increases or tight stitches, a ruffle to extra increases or loose ones.

Check an example round

A practice circle starting with 6 single crochets can double to 12 in Round 2 by working 2 in each stitch. Round 3 can use [sc, increase] 6 times for 18. If Round 3 instead doubles every stitch again, it produces 24, not 18.

Those counts explain one shaping exercise; they do not guarantee a flat circle in every yarn. Stitch height and tension also affect the shape. Compare your work with your actual pattern’s instructions.

Change one cause at a time

Undo only to the first incorrect round when the count is wrong. If counts agree, swatch with the intended yarn and inspect loop height and hook size.

Blocking may relax a slight edge roll when the yarn label allows the method. It cannot replace missing stitches or remove extras. Stop adding heat when the care instructions do not permit it.
