Crab stitch (which is also called reverse double crochet) is a simple edging that you can work with any number of stitches – it creates a diagonal zigzag effect. Crab stitches are just like normal dc stitches but worked in the opposite direction to usual. So work from left to right as described below if you’re right-handed – if you’re left-handed, work from right to left instead and reverse the other directions. To start, work ch1 (the turning chain), but then don’t work into the st at base of chain (the first dc st). Instead, work as follows:
You need to insert your hook into the next stitch to the right. To do this, rotate your hook anti-clockwise so it’s pointing downwards, then insert into the stitch.
Your work should look like this.
Now work yrh…
…and pull a loop through the stitch. Make sure you keep the two loops on the hook at the right-hand side.
Now you can finish the stitch as you would with a normal dc, by working yrh and pull through both loops on the hook.
Your finished crab stitch should look like this.
Repeat Steps 1-6 to make more crab stitches along your edge.
And that’s all there is to it – it may seem a bit tricky to start off with, but as well as making a nice edging stitch it’s also a really useful technique to know, as it can be used in particularly technical designs to help with positioning. It’s another classic stitch that is helped by keeping your tension loose when you first try it, as the yarn can cross over itself making it really hard to pull your yarn through. Always make sure you keep the previous crab stitches to the left of the stitch you’re working (if you’re right handed, and vice versa).
