craftgrrl | Holiday giftmaking with what's in the house

Several years ago, I started a project at the pottery painting studio near my house in MD. I had to paint a large number of three or four inch tiles, fire them, then they would show me how to make a frame for a mirror out of the collection. I never finished painting them and they're in my house in a box. I have somewhere between four and ten of them -- I need to see how many I can find.

This year I am really broke and have a bunch of kids to shop for. I was thinking -- what could I do inexpensively with small tiles, each already painted with cartoon characters on them, for gifts? I've also got shrinky dinks, if that helps.

Edit: I'm cleaning up and just ran across half a tupperware container of multicolored beach glass, too.

Edit: Just found sveral bags of broken mosaic pieces in three or four colors.
