Matisse Cut-Up Repeats
Try these wonderful bold cut-outs, much like the style of Henri Matisse.
Make a little stack of 5 or 6 colored squares, and staple once in the corner to hold together. Then cut one shape from the stack. (Little kids need less paper to cut through easily, and older kids can experiment to see how many they can handle.) Some kids can cut free-hand like Matisse, and others will prefer to draw a shape first.
Matisse cuts his famous paper shapes. When he became too ill to paint, he invented his wild and wonderful paper shapes. He was called a Fauvist, which means "wild beast", for no one had ever created art such as this before.
When he became too ill to leave his bed, he painted his grandchildren's images on the ceiling above his bed using a broom handle with a paintbrush tied to it so he could enjoy looking at them when they were not with him. That tells me everything I need to know.
