"Drawing is very central to the way that I work because it can be blown up, taken apart.... You can just keep on pushing it, like this infinite machine...."
"The white on the dark ground sometimes made blue, so you would have a kind of blue halo- but there was no real blue pigment involved. It was just the white and the dark gray that caused that. I was aware of that, and it all became part of the composition."
