I love working in scratchboard.  It’s a lot like drawing in pencil only in reverse.  You start out with a black sheet then scratch away the black coating with an exacto knife to create the white lines.  Don’t mess up though because there’s no erasing! Since I have a tendency to work soft and omit really dark darks in my drawings, scratchboard is a great medium for me because it’s nature practically forces bold contrast. Here are some scratchboard cats I did last year while I worked for the Monte L. Bean Museum at BYU.
