I covered the walls of both basement rooms with Milino, a cheap substitute for canvas, stretched string backwards and forwards across the rooms and attached widths of packing-paper to them, so that they reached down to the floor and as far as the walls that I wanted to paint. I wanted to create a labyrinth which would somehow help to prevent a compositional idea from establishing itself all too quickly. I had the idea of working on all the walls pretty well at the same time, as if they were one large painting completely surrounding me. By constantly wandering in the labyrinth I sought to realise a form of "de-composition.”.
