Fast and easy way to make pom poms. Great for kids. Use four of these to make a pom pom.
How to:

1. Take two place them so the small dots face each other.
2. Take some yarn/whatevah and twirl around the arch until the inner half circle is full.
3. Repeat for the other two pompom makers.
4. Take the two half circles and slide into each other.
5. Cut the outer layer of string all around.
6. Apply a string around the inner bundle of string and tie a knot.
7. Pull out the pom pom makers.

I havn't tried printing this yet so there might be issues.
