With the low cost of color ink jet printers, most of us have one. I like to buy the manufacturers photo paper and collage frames, to display some of the better pictures I have of my family. Often in this process I print more photos than end up in the collage; I've now found a use for those extra photos.
Take your refrigerator magnets and tape them to the back of the photos. Now instead of the tacky magnets (or throwing them out), I have more photos of the family. Using a scissors, you can cut the magnets to place at either side of a larger 4 x 6 or, cut the photo to better fit the magnet.
