Duct tape

So, I just got an amazing idea, like a smack my head and wonder why I never thought of it before idea. The school supply lists for the little ones have these challenging demands for different colored folders, and while I know it's to keep things straight for the kids and the teachers, it get's crazy to buy two blue, three orange, one yellow.... Soooo, I'm going to buy a bunch of colored duct tape and recycle our old folders by covering them with the duct tape. Then, they won't get torn to shreds by the end of the first trimester, AND we'll be able to use the left over duct tape for other projects. Eureka!
