No, you don't need to buy more containers to organize the kids' stuff. You just need to drink more milk. We really like this idea of re-using milk jugs we found over at Craftzine.
Save your half-gallon milk jugs, wash and rinse, and cut a large opening under the handle. It's the perfect way to lay out craft supplies like the color pencils shown here, chalk, markers, or crayons. The handle makes for easy toting.
Around my house we use recycled items such as clementine orange crates, glass jelly jars, and ice cube trays for craft supply storage. Any other good recycled ideas to share?
