Clothespins can be used to organize and hang papers, photos, and cards when they're turned into refrigerator magnets. To make them, remove the springs from wooden clothespins, and lightly sand wood with sandpaper. Coat with acrylic paint; let dry. Reattach springs, and affix a small magnet to 1 side of each pin with multipurpose cement.
Mighty round magnets; $12.99 for 16; Container Store; containerstore.com.
