On Saturdays I usually paint a two-page spread to use as a planner. Today it is simply about organic shapes and colour. Probably a reaction to the grey day outside my window.
I work two weeks in advance, and each week I move two tabs that say "this week" and "next week" so I can find the pages quickly in my sketchbook. This one is done with gouache. I chose light colours so that the black pen would contrast well.
