Just look at all of that organized craft paint! Just lay down various cans, cookie tins, metal canisters, etc. I used enough cans to almost entirely fill my area. Then I laid in my craft paint in roughly a ROYGBIV pattern. The trick is to face the BOTTOM of your craft paint out. That way you can see at a glance what colors you have. As y'all can see, I am apparently a craft paint hoarder. I think the problem was I never knew what colors I already had so I would just buy new. Not any more!
