Take a look at the jewelry on i love blocks. It just reminded me of some super-fun times making Shrinky-Dinks. I was looking for fun projects for the next two weeks with four kids between 1 and 5... I think I'll have to see if I can get my hands on some of this plastic... I think my Mom use to do it with other plastic too, like from a coke bottle or such. I'll have to check into that. FINALLY something to do with the deluxe, super-sized set of Sharpie (rainbow colored) markers I bought last year.
