 My brush stroke has no system at all.I hit the canvas with irregular touches of the brush, which I leave as they are.Patches of thickly laid-on colour, spots of canvas left uncovered, here or there portions that are left absolutely unfinished, repetitions, savageries; in short, I am inclined to think that the result is so disquieting and irritating as to be a godsend to those people who have preconceived ideas about technique."
