I hadn't thought of posting something as basic as this, but several people have commented on the paint storage system I use in my studio, and since I haven't seen it anywhere else I thought people might find it useful. Basically, I just got tired of having my paint tubes festering in drawers, getting gummy from leaking oil and impossible to find when I needed them. The "system" such as it is, is just hanging the tubes up on readily-available "handbag clips" (technically "Binder Clips" so you can Google them) so you can see all the tubes at once and tell what's there.I have a couple of them--one a shallow box, and the other just a board with nails to hang the tubes from. I attached a couple of picture hangers to make it possible to hang the boards and reposition them if necessary, although I suppose you could just screw the things into the wall (or just drive nails onto the wall if your landlord is a tolerant type). As you can see the method is cheap, easy, and really adaptable. The clips come in several sizes for different paint tube sizes, and it's easy to use the tubes while they're attached. Hope this is useful!
