You will need fairly small pictures to bake in the beads. Digital pictures work best, because they can be easily resized and cropped in a program like Photoshop. Surf the web and find photos of your favorite celebrities or cartoons, or use photos of friends and family.
For mine, I used pictures of flowers. The possibilities here are endless. You do not need to print them on special paper, just make sure they print out to be one inch squares. For best results, they should have a 300 pixel resolution.
Next, let's prepare the clay beads.
