"St Michael’s Church burnt down in early 1960s – it was completely reconstructed. I was commissioned to do something outside on the wall over the main doors. There was a very limited budget. My challenge was working out what could be done in terms of composition and texture. I used sheet bronze for this and developed the piece from a technique of roofing with copper. I first sculpted a small maquette, then a full size cartoon and gave this to metalworkers in town. They did a beautiful job because they knew the technique so well."
