"First thing in the morning I switch on Radio 4. It signals the start of my day. Much of my work involves built up marks made with repetitive gestures. The layers develop Ìýorganically through the tempo of the radio. I'm at full Ìýspeed around Woman's Hour, in auto pilot by the Afternoon Play and winding down to easier tasks by The Archers and Front Row. It's my daily metronome."
