I can't stand to paint ACEO size all the time. I have to just do it once in awhile. When I do, it's difficult to choose a subject, unless it's individual flowers. I do find that cat portraits make a pretty good ACEO subject, though. And they're fun. This one is a Golden Persian, one of my childhood pets. Her name was Frisky. Pretty original name.
