Materials are critical ... And I love the glass. I don't know exactly why, psychologically, but I love the jewel-box thing with the frames. I saw a Francis Bacon show in the '60s at Marlborough Gallery in New York, and he had his paintings framed this way. I loved his paintings, and the frames just put them through the roof. I said, 'If I ever get money, I want to do that.' I don't have money, but I have enough to do it.
