I went into a art/craft shop the other day and found these great foam stick ons. my ds spent about 1 hour this afternoon, constantly peeling off the backs and making creative pictures for the world to see (well me anyway), absolutely fantastic idea, no mess with glue, and kept him amused and in a creative mind set. he had a ball! all they were were different shapes, like circles, squares, triangles and in different colours to. great!
