Scratchboard original, Snow Leopard. Scratchboard is a piece of 1/8" thick piece of masonite with a thin layer of white plaster covered with black India ink. You scratch on the inked surface and it comes up white. Many thin scratch lines give you a light value in appearance. I find that animals with fur are the easiest image to scratch. Visit my YouTube site called Scratcboard Art & Stuff and you can see me scratching large cats and other images. Hope you enjoy.
