8/11. The term "Newton" was genius, like "Kleenex." These were made by Kroger so sadly they're just bars. I started with a pencil sketch and the painting might have worked better if it was done sketchier. I tried an oil primer (on top of the acrylic gesso) which I've used many times long ago, but I had a hard time working wet on wet. It would be the ideal surface, however, for another session if such were to take place, and for a virtuosic landscape sketch at Italy's Lake Como if I were R.P. Bonington.
