My daughter received the Shrinky Dinks book for Christmas, and the whole family is having fun making them and watching them shrink. My daughter (age 6) is making them into jewelry with her wire art kit and some other craft combo's. The rest of us aren't quite sure what we'll do with them, but they're really fun. Girls seem to catch on to them first but boys like them once they realize that they can draw anything - not just flowers and hearts. The shrinking process is very easy (about 2 minutes), and not messy at all. We're going to buy more sheets - not because we need them yet, but because my husband wants to make some bigger Shrinky Dinks.
