Reverse Single Crochet or Crab Stitch (abbreviated reverse sc, rsc or crab st)

Reverse single crochet, sometimes called the crab stitch, is a decorative stitch. It is a single crochet worked backward across the project (i.e. from left to right if you are right-handed). This creates a little textured bump. Reverse single crochet is generally used on the edges of projects, but it can be used in the body of a crocheted piece for texture.

Note: Crochet does not have standardized naming conventions for special stitches. Designers may call stitches by whatever name they prefer. For this reason, it is difficult to search online for how a particular special stitch is created. Another reason it is hard to find the “correct” way to work a particular special stitch is because each designer might work a special stitch in their own unique way. Be sure to follow the directions stated in your pattern for how to work the stitch. 

Instructions
