This is ‘Wookie’my largest watercolour I have done to date. He is painted on A2 mountboard, which I then painted with clear gesso. This started as an experiment, testing which items I could use watercolour on, after priming with clear gesso. It also allows for painting watercolour on a canvas after being primed in the same way. You can purchase a medium specially designed for this purpose, but I had clear gesso, so gave it a go.
