Sometimes I like to prepare sketchbook pages by painting random colour washes and splotches, letting them dry, then (often much later) drawing something completely unrelated on top. I know this isn’t to everyone’s taste, but I like the unpredictability and spontaneity it can give to sketches. It’s the opposite of traditional watercolour technique. Here are some examples. They really are ‘sketches’… not meant to be finished paintings or fine art!
