Have you ever finished a project and found that you're not quite happy with the edge? Perhaps your crochet scarf needs a tidying up or your knitted gloves are rolling at the cast-on edge? Crab stitch—or reverse single crochet—is a simple edging that adds that little bit extra.
Crocheters find many uses for this finishing technique, but crab stitch is great for knits and woven fabrics, too. Angharad Thomas added a crab stitch edge to stablize the cuff of her Glorious Gloves to Knit in PieceWork Spring 2022. This smooth finished edge paired well with the fine silk yarn.

I'm a left-handed crocheter, and this technique works equally well for both left-handed and right-handed crocheters. The difference will simply be in the angle of the stitches. The other differences here are in my tension between my left and right hands. In both cases, I found that keeping my stitches looser than I would for my default crochet tension helps to make it easier to work and keeps it more even.

Crab Stitch Edging (Reverse Single Crochet)

As the name implies, this edging is worked in the opposite direction along the row. These illustrations assume you are working with the hook in your right hand (right-handed crochet), and the crab stitch edge is worked from left to right along the edge. As shown in the illustration, attach a new working yarn if needed.
Insert the hook into the fabric edge, pull up loop, yo, pull through loop. (Rotating hook down, insert into previous st, yo, pull up loop, yo, pull through 2 loops) rep for each st across, finish off.
Here is what it looks like on the back of the work:
