My studio is an ABC playground. I study painting’s first principles. I’ve learned that any flat surface has two main sides; I call each side the first and second surface. The face or first-surface of a painted picture is conventionally “a painting”; the first surface provides us what is called a “picture”. A painting is also an object: generally flat-faced and a type of shallow relief. It has depth and sides; a painting has a back side. The back of a painting is its second-surface. I paint the front and the back of a surface. They are double-surface works.
