I have worked to free shape from its ground, and then to work the shape so that it has a definite relationship to the space around it; so that it has a clarity and a measure within itself of its parts (angles, curves, edges and mass); and so that, with color and tonality, the shape finds its own space and always demands its freedom and separateness.

The negative is just as important as the positive.

All my paintings are usually done in drawing form, very small. I make notations in drawings first, and then I make a collage for color. But drawing is always my notation.

I did not want windows, only skylights. I chose my painting wall as it has the best morning light.

My forms are geometric, but they don't interact in a geometric sense. They're just forms that exist everywhere, even if you don't see them.

In drawing, I don't erase. I believe the original gesture has to be the best.
