I bought a nice wooden frame with a colander of apples in it for .50 a couple of years back. Today I finally had the time to fix it up properly by adding ribbon, buttons, fabric scraps, and an old glove. It turned out really nice.
Updated: This idea came to me when I was reading about laminated wood products. I decided to try it out using cardboard and craft glue and came up with a very strong but very light wood substitute.
Even if you don't have a frame, you can make your pictures look decorative with colored duct tape! Add a magnet to the back and you can display it on your refrigerator with pride.
