A Sock is a wonderful thing. It can warm a foot, that's for sure. Better yet, it can become a zillion different critters.
Sock puppets are easy to make.
All you need to do is start with a sock. Put the sock on your hand so that your fingers and thumb are in the toe and the back of your wrist is in the heel. To make room for your puppet's mouth, make a slit in the sock between your thumb and fingers. After the glue has begun to dry, fold them in half the short way. Sew folded oval into your sock.
