The center single crochet can go by a few different names. You may have heard it called the waistcoast stitch, the knit stitch, or the v stitch. Whatever you call it, this stitch is a slight variation on the single crochet that creates a neat, close stitch. Scroll to the bottom of the page for the video tutorial.

Center Single Crochet (csc)
The center single crochet (csc) is worked exactly like a single crochet, but in a different space than a traditional sc. Insert hook into the “center” of the stitch (between the “v” shape) rather than the top two loops. See the image to the right.
