Before you start, here are a few things you should know:
2) Before you begin a project using the loop stitch, be sure that your loops are coming out the same size. Otherwise, you will have a fabric full of different sized loops, and no one wants that (or do you?).
3) If you are crocheting a stuffed animal with loop stitch, and you are starting with a circle, instead of crocheting 6 loop stitches into the ring, single crochet the required amount into the ring. Then for the next round, loop stitch following the instructions for the pattern you are following. By making the first round single crochet, it will be easier to work the second round (which will be in loop stitch).
