Matt's parents gave us these really cool picture frames for Christmas that are designed for displaying kids' artwork. They open with a hinge and each holds up to 50 sheet of paper. Last week I finally hung them up in our playroom and they look great. Henry and Oliver made some new artwork to display and Oliver even "helped" me hang the frames!
(I wasn't able to get a very good picture because of the glare on the glass, but this gives you the idea.)
