Techniques. One coat of paint is left to dry on a canvas or sheet of paper. Another coat of a different color is painted on top of the first layer. The artist then uses a palette knife or oil stick to scratch out a design, leaving behind an image in the color of the first coat of paint. Sometimes a first coat of paint is not needed and the wet coat scraped back reveals the canvas. This technique is often used in art classes to teach the technique to novice art students.
