I saw this tutorial a while back and finally had time to try it:

I made this one as a little gift I'll be sending out in the mail shortly :) It's entirely made of leftover chipboard and paper.

I followed the tutorial, but did cheat a little when it came to making the filled in area on my pendant... I used Dimension Magic instead of just Modge Podge for that!
