I recently purchased a really fun book for making jewelry for Teens and Tweens out of Polymer Clay. It is called "Clay So Cute!" by Sherri Haab. I have tried a few things from the book and they are easy and really cute. If you have Tweens or Teens in your family, encourage them to join you in making their jewelry.
I highly recommend that you check out this book. Sherri's website is http://sherrihaab.com/
