Tryfan, Light on the Ogwen Valley, gesso mixed with marble dust powder, watercolour ink, acrylic and oil on canvas, 271⁄2x391⁄2in (70x100cm).
‘I often use interior designer palette knives, which are more robust than artists' palette knives, and rags to apply gesso base layers. When dry I applied thinned oil paint to pick out the craggy base surface. I then applied thicker layers of oil paint to bring in the detail. The light in the Ogwen Valley is remarkable, and this composition was a lot of fun to create.’
