We're always game for inexpensive framing ideas, and free framing ideas? Well, that's all the better. Gather up a cardboard box along with any photos that are collecting dust and give this simple project a try...We also like the thought of using these frames for holiday decor - you could cut out holiday shapes for the frame (or not, either way) and string them together around the tree, mantle, or anywhere really. You can even glue some wrapping paper over the cardboard for a little festive boost.
