Q: How do you decide when a pastel painting is finished?

“Magisterial,” soft pastel on sandpaper, 58” x 38” in progress
A: During the months that it takes to create a pastel painting, I search for arresting colors that work well together. The goal is to make a painting that I have never seen before and that leads the viewer’s eyes around in interesting ways. To do this I build up and blend together as many as 25 to 30 layers of pigment. I am able to complete some areas, like the background, fairly easily – maybe with just six or seven layers of black Rembrandt pastel. The more realistic parts of a pastel painting take many more applications. In general, details always take plenty of time to refine and perfect.
No matter how many pastel layers I apply, however, I never use fixatives. It is difficult to see this in reproductions of my work, but some of the finished surfaces achieve a texture akin to velvet. My technique involves blending each layer with my fingers, pushing the pastel deep into the tooth of the sandpaper, and mixing new colors directly on the paper. Fortunately, the sandpaper holds plenty of pigment so I am able to include lots of details.
Before I pronounce a pastel painting finished, I let it sit against a wall in my studio for a few days so I can look at it later with fresh eyes. I consider a piece done when it is as good as I can make it, when adding or subtracting something would diminish what is there. Always, I try to push myself and my materials to their limits, using them in new and unexpected ways.
