Crab Stitch (Reverse Single Crochet): step-by-step tutorial
Crab stitch, also called reverse single crochet, is a single crochet worked from left to right for right-handed crocheters. The backward direction twists each stitch into a corded, rope-like edge. Crab stitch is used as a sturdy finishing border on blankets, hats, bags and garments.

How to crab stitch (reverse single crochet), step by step
- With the right side facing, do not turn at the end of the last row.
- Insert the hook into the next stitch to the right (left for left-handed crocheters).
- Yo and pull up a loop under the loop on the hook — 2 loops on hook.
- Yo and pull through both loops — 1 rev sc made.
- Repeat backward along the edge, keeping stitches loose.
- Fasten off and weave the tail into the corded edge.
How do you crochet crab stitch?
Crab stitch is crocheted by working single crochet in the opposite direction along an edge, which twists each stitch into a cord.
Angle the hook downward when pulling up the loop to avoid the loop slipping off.
Why is crab stitch so hard?
Crab stitch feels hard because the reverse motion is unfamiliar and the loops twist. Working it loosely, or with a hook one size larger, makes it smoother.
Practise on a small swatch edge of 20 stitches before working a large blanket.
When should you use crab stitch?
Crab stitch is best used on edges that need durability or a firm, non-curling finish, such as blanket borders and bag openings.
It is not ideal for stretchy edges like sock cuffs, because the corded edge has little elasticity.
