Our San Rafael sketching workshop was focussed on creating variety and contrast between two similar items. Variation can result from using different tools and techniques, such as pen vs. aquarelle pencils. Size differences are also effective, as seen in this dramatic sketch by Anne Marie. We went on location to Foot Traffic Shoes on 4th street. Here are more student sketches. A few of us experimented with a rainbow pencil…not water-soluble, but different colors appear as you twist it.
