Foam stamp art, kids thank you cards

We got this idea from parents magazine. We cut up a foam packing piece into a square. Had my daugther write thank you on a piece of paper. I held it up and traced the letters on to the back in reverse. I then placed the paper on the foam and traced over her letters. That left her writing in the foam. I used a pecil to make the inpression a little deeper into the foam. Then she sponged washable paint onto the foam piece and stamped it on the card stock. Cheap and easy, this projet only took a 1/2 hour and we had all of the supplies at home.

foam packing piece
