I switched from acrylic paint for my backgrounds to Ampersand ink and I love the change. I can water down the ink without any issues, and they’re lightfast and archival. With this 6″x8″ piece, however, I went overboard with green and then spent most of my time either toning it down with colored pencil or sanding it off with a fiberglass brush. The beauty of Claybord is that I can use scratchboard techniques for detail and highlights, but using steel wool or a fiberglass brush can erase any mistake nearly down to the white surface. And here are some pictures of Pete having a good roll and then hightailing it back to me.
