If you have taken art courses from me, you know that I don’t buy a fancy palette. I use a piece of white cardboard. Most often this is the center piece cut from a white mat board. On top of that, I used to use a piece of wax paper. Recently a student told me that parchment paper worked better. It is less porous, and will take more scrubbing without deteriorating. The advantage is the same. Instead of having to wash a palette, I simply pull off the used parchment paper and put a fresh piece on when the old piece has become too messy. I use sticky tac on the back of the cardboard for fast and easy switching of the paper. I’m all for anything that makes for more painting time, and less clean up time!
