For binding off the legs:

tip: If you use two crochet hooks to help you pull up all of the loops, it will be a lot easier to complete. Pull the tail
through 2 loops, pull through 2 loops, pull through 3 loops on hook. Starting from the second to the last loop and using a
hook, gently tug on the loop to tighten it up to look better. Not too tight though. Just tighten enough to make it look like
it was a magic ring stitch. Do this clockwise to each of the loops until you are satisfied with the look. When you get to
the last loop, pull the tail of the yarn to make that one neat, and pull tightly to close up the opening in the center of the
leg. It acts just like a magic ring. Just in the reverse. Thread the tail into the inside of the leg
