(Group A) We first covered the whole surface of the paper with a thick layer of oil pastel. Then we went over this colourful base layer with black paint. When our black layer was ready we started to scratch off the paint with wooden skewers. There was a bicycle in front of the children, which they could use as a model for their drawing, but they could also use their imagination, drawing the bike of their dreams and adding a story to it 🙂 This drawing technique encouraged the kids to work faster and to take advantage of the paint still being a bit wet. They also enjoyed the unpredictability of it, when revealing random colours from the base oil pastel layer.
