If you have a Costco close by check out their selection of plastic boxes. They sell the large plastic flat boxes (14 x 14 inside measurement), and they are packaged 5 together, all different colors. All 5 of them cost $19.95. One of the boxes at Joann's was that much and it was clear. At first I filled only 3 and thought about giving away the other 2 but wouldn't you know it, they are all filled now without even trying.
