Art project: Eric Carle-style art

I've always been fascinated by Eric Carle's techniques in books like The Hungry Caterpillar and Does a Kangaroo Have a Mother, Too? So we tried a version of this technique last week. My kids are still a little young for their art to look as cool as these student examples, but it was fun to try. I also tried making pictures, as he did, by cutting shapes out of photos in magazines. Maybe I'll have the kids try that this week.
