Sometimes you need to stop doing something to really see it afresh.

For me looking, touching, material, place and form are all inseparable from the resulting work. It is difficult to say where one stops and another begins. Place is found by walking, direction determined by weather and season. I take the opportunity each day offers: if it is snowing, I work in snow, at leaf-fall it will be leaves; a blown over tree becomes a source of twigs and branches.

One of the beauties of art is that it reflects an artist's entire life. What I've learned over the past 30 years is really beginning to inform what I make. I hope that process continues until I die.

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.

You must have something new in a landscape as well as something old, something that's dying and something that's being born.

Not being able to touch is sometimes as interesting as being able to touch.

The British climate, although it is very wet, it is quite mild in winter. We don't get these severe - generally don't get severe winters.
