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.
Before you start: Crochet in the round
Match the visible symptom
| Shape | Where to look | Try this first |
|---|---|---|
| Flat rows curl from the foundation | Starting chain and first-row tension | Compare a short swatch made with a looser foundation. |
| A round cups like a bowl | Missing increases or tight stitches | Compare every round total and increase placement with the pattern. |
| A round ruffles at the edge | Extra increases or loose stitches | Count the last flat round and the first wavy one. |
| A border pulls the body inward | Attachment frequency along the edge | Undo a short border section and reassess its spacing. |
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.
