Sutz writes: "After making life masks for over 50 years, I found a procedure that seems right for me. My subjects sit upright in a comfortable chair, breathe normally, and can keep their eyes open. I lubricate the face and hair, and apply a mold-making material (usually plaster bandages). I work my way around the nostrils and eyes, making it easy for my subjects to breathe, while their eyes can be opened or closed. This procedure usually takes about 45 minutes, before the face mold is removed. After the cast is made, the eyes are carved out and the hair is modified."
