I brought my family to the Stone Arch Festival of the Arts in Minneapolis Mn this weekend. We got some really great ideas from and organization called ArtStart. ArtStart is an award-winning,non-profit arts organization dedicated to providing quality arts education for children and adults. They had a activity book with a great idea. Here is a way that you can reuse CD cases.
It looked as if they were using Elmer's Glue and a variety of beans. The one on the right also has a mirrored sheet of paper in it.
