Reverse single crochet (also known as the crab stitch) is worked just like a regular single crochet, but in the opposite direction. This simple shift creates a beautifully textured, cord‑like edging that gives your projects a clean, polished finish.
How to Crochet the Crab Stitch
STEP 1:
Insert the hook into the stitch to the right from front to back.
Left‑handed crocheters: insert the hook into the stitch to the left instead.

STEP 2:
Yarn over and pull up a loop.

STEP 3:
Yarn over again and pull through both loops on the hook.
