This would be a distortion of their meaning, since the pictures are intimate and intense, and are the opposite of what is decorative; and have been painted in a scale of normal living rather than an institutional scale.
I also hang the largest pictures so that they must be first encountered at close quarters, so that the first experience is to be within the picture.
Since my pictures are large, colorful, and unframed, and since museum walls are usually immense and formidable, there is the danger that the pictures relate themselves as decorative areas to the walls.
