WG's hack will help you make sense of the incoming avalanche of art:
My kitchen had a fridge that was covered in paper and some blank walls that were crying out for decoration. I like the idea of framing kid art and displaying it, but not every piece warrants a frame. So I picked up some steel wire and some funky clips (total cost: under $5), and my husband stuck a couple of screws into the wall to create an instant art showcase.
We can hang the art we'd like to display without going to the trouble of framing it. The best pieces can ultimately be added to the memory box we keep for each kid; the ones that are nice for a short time can be replaced with newer pictures as needed.
The front of the fridge is now pristine black; the invitations and reminders are all stuck on the side. Result: a cleaner look and a lot of smiles.
