Sometimes we can’t find a place for storing books, and a couple of bookends can help to fix them in any place. The supplies are a milk carton, scissors, packing tape, rapid set concrete, a mixing tub, a stirrer, a cylindrical object, sandpaper, painter’s tape and granite spray paint. Start off by cutting your milk carton in half. If you made the initial cut in your milk carton through the spout (which is what I did just because it was easier), then stick the top half of your milk carton together again with packing tape and also seal off the spout-end. Mix your concrete according to the manufacturer’s instructions and fill both halves of your milk carton. Head over to makeandtell.com to continue reading the tutorial.
