I start to apply color in almost a crosshatch design. This step takes a while because I only do 2 - 3 strokes and then step back. I'm not only choosing design structure but also color hue and tone. I like the feel that evolves as I determine areas that will actually show through from the toned part of the canvas. Sometimes things happen that are a surprise- good and bad - but that is always part of the painting process and life.
