If you have not discovered Perler beads yet, you are missing out! These little beads can make a variety of things, including but not limited to coasters, necklaces, bracelets, and just fun little pictures.
All you have to do is create a pattern (or find one in a Perler book or on the internet), arrange the beads on a peg board, iron them (with ironing paper), and then let them cool. It is also fun to glue magnets on the back of them to put on your refrigerator!
