Many people can’t believe that my very realistic animal artwork is created just from scratches into an ink coated board, but that is exactly how each of my works is drawn. I work in the amazing medium of Scratchboard, which helps bring my animals and wildlife to life in a hyper-realistic way that no other medium can!!Scratchboard is a unique medium because it is subtractive. I start with a solid black ink coated board and scratch away the ink with sharp tools to reveal a layer of white clay that is beneath the ink.
