Mel and Dorothy Tanner worked with the same material, acrylic glass, in very different ways. Dorothy liked to have a lot of material around and then begin her construction. Mel Tanner always sketched first, often filling the sketches in with colored pencils so that they were very precise. The drawing(s) very closely resembled the completed sculpture.
Here are some examples of Mel Tanner’s sketches compared to the photos of the completed works:
