School or art themed decoration ideas?

I want to use shadow boxes to make a series of wall hangings that are fun and appropriate for my daughter’s room. I have one idea, but would like a couple more and I’m having trouble coming up with any.

The first one is a shadow box filled with new, sharp crayons – kind of like the were tossed in a box. I would glue a first layer to make a solid background then glue a couple of additional layers with crayons going in different directions.

It is colorful and playful. Any other suggestions on art or school supplies for a couple of additional shadow boxes? I would like to make a set of three or four. Colored pencils and markers seem too similar to the crayons.
