And if you've noticed in these pictures, I use a lot of plastic bins to store supplies. They are inexpensive and easy to stack. Separate your supply stash into the different boxes, label them and you are set! You can even pretty them up if you are so inclined. In this cupboard below you can see small plastic bins on the top shelf for my stamps; on the third shelf there is a bin for my kids art supplies, and one for my paints, and on the fourth shelf there is one for my paper stock!
