Thumbprint Charm

This is such an adorable idea that I found on the web. Instead of your guests signing their names, they leave their thumbprint. And the bride and groom are left with a super cute piece of art! I think this would also work for birthday parties. I especially like this bike and balloon look. It would be a cute idea for any age - 1st birthday or even a 10 year old. Cuteness!
