I can’t resist the magic of discovering what happens by creatively combining accident and intention. A few years ago I was fascinated by this technique of using resists with sprayed paint. The small painting above uses white oil pastel and watercolor and ink. The pastel lines are not very visible as you make them, so putting them down on the paper means laying down a swathe of line somewhat blindly, by feel more than sight. I then sprayed the color over it and the white lines appeared.
