I’ve put the first day’s work (painting) up again because I didn’t realize I had put up a thumbnail. this should be easier to see.
This piece is on stretched ( WN) canvas. The canvas was coated with several goats of Acrylic gesso and allowed to dry. I actually painted the gesso on leaving it with a rough texture that is more or less going across the canvas as the water is. I think if you click on the picture it will enlarge. Perhaps you can see some of the texture. If you have never done this, it can be fun. You can use just about anything from a spatula, sponge, fingers, bristle brushes and drag these things thru the moist gesso to leave marks. Then allow it to dry.
