then attach it in the next stitch after where you started.
stitch one in the circle after your ear and chain 10 to make the little hanger. the one i saw didn't have a hanger. you could sew it on something or pin it guess, but i like the hanger. leave it off if you don't. after your chain 10, attach it back in the same stitch.
now stitch inside your circle down about 3 or 4. you need enough room for 2 legs on the bottom. otherwise you have a legless pig, and that's just sad.
i chained 3 and did a half double, (pulled one through, yarn over and pull through both), then chain 2 and attach all in the same stitch. put a couple of stitches between and make the other leg the same.
then i just pulled it up, cut it off and weave in the ends
