Reverse Single Crochet

The reason why it is called crab stitch is that a bit like a crab, you walk/crochet backward!

Instead of crocheting from right to left (if you’re right-handed), you’re going to crab stitch from left to right.

In a similar fashion, if you’re left-handed, you’re going to invert the direction of your work from left-to-right to right-to-left.

This is the reason why the crab stitch is also called reverse single crochet (RSC) because you make single crochet stitches in the opposite direction than usual!

After a crab-stitch row or round, it’s very difficult to crochet on top of these reverse single crochet stitches. So normally, this stitch is used to give a quick and easy finishing touch to any project, be it a blanket, a scarf, a basket, etc.

Crab Stitch (Reverse Single CROCHET) BORDER – VIDEO TUTORIAL

For both my video tutorial and the step-by-step photo tutorial, I’m going to show you how to add a crab stitch border around a simple circle granny square.

The last round of my square is all in double crochet stitches, but you can work the crab stitch border on any stitch you have!

However, if you have a lace stitch pattern, I do suggest you add a row/round of single or double crochet before working your crab stitch border.

How to Crab Stitch at the Corners

At the corners, you do not need to do anything special.

Just keep crocheting crab stitches in each stitch, chain-1 or chain-2 space you have. Then, continue crab stitching on the next side!

How to Finish off the Crab Stitch Border

To finish off the crab stitch border and make the joining point as invisible and seamless as possible, make one last crab stitch in the same st where you joined the yarn.

Then, fasten off and weave in your ends.

Some people find that the joining is more subtle if you do not make that last crab stitch in the same stitch where you started.

Instead, they simply slip stitch in the initial stitch, fasten off and weave in their ends.

I don’t particularly like this method because I feel like there is always a little gap in my border.

But feel free to try both methods and choose the one you like better.
