I think I have been fashioned by the fickle weather of Britain that it is - it's forever changing. There's no kind of constant sun or dry weather or freezing weather, and I'm always having to change and adapt to that.

The main source of my income is through the commissions of the large-scale works and big sculptures, the projects.

In contact with materials, I can see so much more with my hands than I can just with my eyes. I'm a participant, not a spectator. I see myself both as an object and a material, and the human presence is really important to the landscapes in which I work.

The difference between a theatre with and without an audience is enormous. There is a palpable, critical energy created by the presence of the audience.

As with all my work, whether it's a leaf on a rock or ice on a rock, I'm trying to get beneath the surface appearance of things. Working the surface of a stone is an attempt to understand the internal energy of the stone.

I can't edit the materials I work with. My remit is to work with nature as a whole.
