Sometimes you won't use all the paint you put out. Nothing is more annoying then when I put out paint and don't use it. It gets a skin and it's done. If you feel this too, then get your palette knife and some old support. Make a simple study from palette scrapings. It's fun and instructive! Don't worry over it, don't do a drawing under it. Just practice mixing the right color, value and shape. Place them in their relative proportions. The more you paint, the more you learn!
Below is a small (8x10) palette knife study done with palette scrapings. Try it.
This idea is not mine, I read it in a Richard Schmid book years ago. Thank you, Richard
