I made this cute collage out of black and white photos today. It's an eye catcher in my kitchen! I laminated the photos (backed with a layer of thin cardboard paper to give it more stability) and then punched small holes into the corners and assembled the whole thing with key rings. You can get photos laminated in most copy or photo shops and key rings are available in stationary shops. For the punching of the holes I used a standard hole punch for paper. Instead of photos you could laminate your kid's art work. That should make for a wonderful collage too!
