I got a few 5x7 inches panels, and decided to make of them an abstract warm ups. Since I kind of dislike working on small surfaces I did a little trick I learned from a fellow artist - put them on a table side by side (putting a sticky tape on a back so they won't slide), two rows with three panels in a row, total six panels. Then I was painting them as though they were a bigger surface. That way I was not limiting my brush trying to squeeze inside a small panel.
More of them to come. Stay tuned.
