Half Gallon Storage From Tina Kimbley, an elementary teacher from Long Island, New York: "As student mailboxes or for just sorting out the days/weeks worksheets, I use half gallon juice containers. Since they are made of waxed cardboard, they're sturdy. Bind four together with clear cellophane tape. Then bind two more at a time until there's eight across. Make another row going across or shorter columns if there's limited space. I've had up to 35 cartons in a rectangle without any wilting problems. It certainly costs less then the store bought cardboard kind. If you're really passionate about one kind of juice, it helps create a theme."
