I met Mary [Hamill] in New York at my exhibition and when I told her about my oral history project she asked, "Would it be possible to incorporate visual art?" My sister stitches pillowcases, which led to Mary suggesting using cyanotype on them. I originally thought of the idea of pillowcases because when people get married, they have the bride and the groom lay their hands on each other's pillows while their relatives tie ribbons on their wrists. And then on the bed you usually have two pillows - one for yourself and one for your loved one - so when one is gone, one pillow remains.
