Yes, When you are done painting a room, take the canvan up and add some more paint by brush or roller, and take a sponge or cloth and smear the paint around.
My husband and I opened a photo studio and couldn't afford many pretting backgrounds, so I bought a very large canvas background cloth and used regular household paint. We mixed colors of paint and just went after it. After it dried overnight if we wanted to add more color, we did until it got just right. I think we still have one we painted with brown paint toned down with white and in places we added some blue paint toned down by various amounts of white. It was fun to do. At first they were really stiff, but after using for a while and after I washed them they softened up.
