I limit materials. Three color values, no mixing. Often only one brush. I work with heavy-duty canvas on heavy-duty stretchers, and a heavy-duty aluminum easel. Although I only work with the canvas clamped to the easel in the traditional manner, I frequently move the canvas between the clamp and the floor. I completely erase most canvases multiple times leaving an even wash of an arbitrary color. I make evolving series (plural) of marks. The mark-making becomes affirmative when I am approaching the solution to a given painting. The physical and mental planes align. The painting is a record of this experience.
