I create my oil paintings in multiple layers, with a first layer being done quickly and loosely. After they dry, I sand these painted “sketches” before painting over them in complementary colors. I build subsequent layers primarily with a palette knife which glances over the surface allowing much of the prior painting to show through. I continue to layer color and composition, often sanding in between, until the painting is resolved and the layers of complementary color appear to glow. The use of the pallette knife also eliminates brush strokes and creates a variety of surfaces and coverages.
