Make Harry Potter shrinky dinks. I just used permanent markers and drew silly pictures and then just followed the directions on the package. Remember they will shrink down to be about 1/4-1/3 the size. Set aside. I like to put different Harry Potter icons like the snitch, Hogwarts castle, rat, glasses, characters etc. and I like picking beads and buttons that represent the different Hogwarts house colors and animals.
