Sketchbook Still Life

When I thought about doing this sort of still life, I was surprised I hadn't done it yet! I enjoy seeing other artists' painting setups, so here's a glimpse of mine: my little paintbox (small and portable) with its portable brushes, a handy waterproof ink pen, water jar and paper towels, and my sketchbook, of course.  I can go almost anywhere with this, in the hope of taking advantage of any sketching opportunity that presents itself. Pen and watercolor, 6" x 8".
