This round piece of plywood was for sale at the Habitat store for $0.75. I couldn’t resist, but only got two. Now they’re gone. They came from speaker cabinets. 
I screwed it to the other board to work on it. The squares are mat board, to refer to QR codes. It isn’t taking the paint the way a flat surface would, so it’s hard to stay loose, when I keep running into edges. But as in oils, I do better when I keep adding paint. Now if I could only figure out how to get a pic on FB. I’m a Luddite on dial-up.
Painting as I see it.
