Remember that stack of styrofoam plates I bought to make stamps? Well, I switched to recycled styrofoam meat trays for my stamp making needs because they're thicker. So what to do with all those plates. I found out they make the best disposable palettes! Even better, when leftover paint dries on the plates I can stack them (dried paint and all) out of the way. Whenever I need a color, I can browse through the stack and usually find it. Why didn't I think of this sooner?
