It takes between three and six hours to make each snowball, depending on snow quality. Wet snow is quick to work with but also quick to thaw, which can lead to a tense journey to the cold store.

Even in winter an isolated patch of snow has a special quality.

Photography is a way of putting distance between myself and the work which sometimes helps me to see more clearly what it is that I have made.

The first snowball I froze was put in my mother's deep freeze when I was in my early 20s.

The reason why the stone is red is its iron content, which is also why our blood is red.

I have walked around the same streets so many times, and then seen a place that had been hidden to me. I now know the sites in a way that makes me think I could have made better use of the connections between place and snowball.
