I've seen a wide variety of tutorials all over the web showing a very basic way to make your own stamps out of craft foam. Most recently over at Kids Matter where Angie made some wonderful butterfly life cycle stamps.
Being that we are currently observing the life cycle of frogs, I thought I would make a bunch of stamps for the frog life cycle. The children thought it would be fun to make their own too.
We glued the foam to a piece of hard cardboard with rubber cement, and added a piece of cork to the back with a hot glue gun to make our stamp.
Dane was really excited about learning this technique - He made a couple of mixed up animals today, but has plans for an entire zoo of stamps!
