I was also reminded that I put a round of reverse single crochet over the stitches of the cast on. It is the same as regular single crochet, except you are working from left to right, giving the stitch a twist in order to make it work.

With one st on hook, insert hook into next space/st, yo hook, and draw loop through, yo hook and draw through both sts on hook.
Repeat.
