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

In Paris in the late '40s, I started making my first reliefs. They are separate panels. I wanted to do something coming out of the wall, almost like a collage. I did a lot of white reliefs when I started because I liked antique reliefs, really old stuff.

I'm interested in the space between the viewer and the surface of the painting - the forms and the way they work in their surroundings. I'm interested in how they react to a room.

Geometry is moribund. I want a lilt and joy to art.

I don't labor over my drawings. I want to get freedom in the line.

One of the first drawings I did in Paris - I wasn't thinking of doing drawings, but somehow or other, I kept drawing - I bought a hyacinth flower with a lot of leaves, just to make me feel like spring.
