36"x48" canvas, oil. Sometimes you need to attack a canvas. I love how a new layer hides and reveals that which came before. Oil does at times test my patience, waiting for it to dry, but I have three large canvases (the other two are 30"x40") and not enough time to lose myself in paint. I adore playing with color and I'm using my white a lot less lately--truer pigments that haven't been washed out are powerful.
