My abstract works are process-driven and I usually begin by mark-making and laying down shapes, images and color fields. Once a satisfying series of marks is laid down, I add oil and cold wax, layering with texture and color. Areas of the painting can then be scraped back to reveal what's underneath. I like discovering these remnants of earlier marks and it allows the history of the painting's development to become visible. Color choices are initially negotiated intuitively. As the painting develops, and using a form of painterly logic that is intrinsic to the work, those choices become more and more analytical. If you look at your work long enough, it will tell you what to do.
