A few weeks ago I was invited to teach a watercolor workshop at a local high school. The students chose subjects for a painting from their "concentrations", a body of work related to their chosen concepts. The assignment was to find an interesting perspective for subject placement that would feature cast shadow shapes within the composition. Since watercolor by nature is a transparent medium, the paint works well to describe the transparency of shadows. We worked on Ampersand Aquabord, a textured clay surface that has many "forgiving" properties for beginning watercolor painters (most notably, the ability to life out and subtract paint and correct errors).
The class jumped right in without fear, worked hard, and created some amazing work.
