Abstract art suggests for most people a large oil or acrylic canvas, but a smaller work in watercolour has possibilities too. I am working on a series of pictures that express emotional buoyancy with an outburst of coloured shapes leaping up against a colour-contrasted background. The shapes are created by splashing masking fluid onto the paper and tilting it back and forth. When the fluid is dry, I paint the background. Once that is dry, I remove the masking fluid, and add a spontaneous choice of two or more colours to the the newly-exposed white shapes. It’s fun to play with colour and shape without reference to objective forms.
