This painting is based on a sketch from one of my sketchbooks. I drew the sketch on 110-pound cover stock paper with a black grape Prismacolor pencil. I like to draw on heavyweight cover stock because it takes a lot of abuse and generally has a very nice surface on which to sketch. The black grape Prismacolor pencil is a nice dark, somewhat gray, violet color.
I scanned the original sketch at 300 dpi (dots per inch) for this tutorial. I reduced the image to about half of the original scanned size. Reducing the size was mainly for convenience when working with the image and because I generally knew how large the image would be printed.
