As requested, here are some photos of the Crab stitch, also known as the reverse sc for left handed crocheters. Above we start with 3 rows of sc, ch 1 at the end of the row, but do not turn. Now begin working back the way you came.
The first one looks funky. It's not until you get a few that it will start to look right.
The hook above shows you where to put the next stitch. Insert the hook, yo, pull up a lp, yo, and pull through two (both) lps on hook, crab stitch made.
