I learned the rub away technique during my studies in South Africa a long long time ago. The principle is very simple. Place some paint on a surface and rub it away using a cotton bud. But simple doesn't always mean easy. This technique takes time to be mastered and a lot of patience. The painting above was done during my studies and portrays a shepherd with her dog. This was done on cardboard with two colours. Burnt Sienna and Prussian blue placed in diagonal strokes. Then the colours were patiently taken away and some paint added ( the white) to give a dramatic effect. In the painting below, a small shed in Rodrigues, some additional colours were added. The strokes you can see on the paintings are placed in gesso primer before starting the work.
