Materials you will need:
1. Trace a small circle (about the size of a cup) onto a piece of white cardstock. You don't want it to be too big, because you need to be able to get your hole punch to reach into it to punch the holes.
2. Draw 2 curvy lines on each side of the circle with a marker.
3. Using a hand-held hole punch, punch holes on both sides of each of the lines.
4. Cut a long piece of yarn and put a small piece of tape around one end. This will help your child lace the yarn through the holes. Then tape the other end onto the back of the baseball so it stays in place.
