How to Hold a Watercolor Brush
Becoming a good watercolor painter means learning how to control water with the brush. A watercolor brush is thick at the base, designed to hold a lot of water since we do lots of washes; and pointy at the tip for detail work. When painting a wash, the idea is to move a controlled puddle of colored water across the paper, and the brush must be loaded. Your paper should be taped to a drawing board that is set at an angle to let gravity help you control the water. Tip the handle of the brush up as you paint so that the water flows out the tip and doesn’t run back into the base of the brush.
