Charles likes to keep his paints clean by using two pallets. He will keep his paints on one, and mix on the other. He uses a combination of pallet knife and brush. Typically he’ll lay in the entire painting’s background and sky first. Then he has to let that dry before he lays in the foreground. It may be days or months later before he gets back to it. He finishes it off with highlights of light and shadow to bring out the drama in the picture.
