Left: A different squash made its way into the house. I sketched it with a Faber-Castell Pitt Artist's Calligraphy pen. Then I painted it with layers of gouache. Click on the image to view an enlargement.
One of the fun things about painting on Gutenberg paper is that the pebbly texture of the paper allows you to include interesting textures in your sketches. As a final touch on this painting I rubbed a dry brush of dark blue paint across various areas of the lighter colors. This helped create shading and round certain areas, and provided an interesting speckled texture to the squash.
