My hobby sometimes is portrait painting with acrylics. I start with a pencil drawing on canvas board, then paint an outline, then flesh the rest in. I don't paint so much now that I have a digital camera. Once my cat leaped onto my paint palette and smeared himself with oil paints. I had to give him an immediate bath in the sink which he hated. To this day, I still have the slash mark scars from his frantic efforts to escape the bath. (I wish I had a digital camera for that event.)
