Using wooden balls for Santa's head, glue on a pair of jiggly eyes or paint some eyes. If you have Christmas clipart graphic images, you can cut out a picture of Santa's face and glue it to the ball. Glue the ball on the top of the ornament. Then add cotton to serve as his hair on the head, mustache and as his beard.
