Long ago my daughter and I were making Christmas Decorations using the classic Shrinky Dink baking plastic. You could draw on it, cut it out, bake it, watch it shrink down, and then throw a loop of ribbon in it and you had an ornament.
After we had finished a batch, my daughter looked at me with glee, held a small tree up to her ear and said, "Look at this!".
THAT was it. I was hooked. About 3,000 different styles of cute plastic earrings, 200 craft shows, and at least five canopies, here we are.
