We did this project in two steps. The first step was to color the entire paper in oil pastel. We used abstract designs and tried to cover the ENTIRE page. Next, we painted a layer of black tempera paint mixed with a little bit of dish soap over the top (the soap helps the paint scratch off). After the paint had dried, we spent the next class period “drawing” with toothpicks. The paint layer was easily scratched away leaving behind the colorful oil pastel below.
