Prunella Clough has explained that:
visual themes and images recur again and again. She likes seeing through things: glass, for example, and nets and space frames of one kind and another. There is an early Greenhouse to be seen here, a later series of landscapes through a window; the early fishermen's nets find their equivalent in last years wirescapes. She likes the sudden intrusion of something hard, and usually rectangular, into softer areas of indeterminacyit might almost be said that she turns everything into a still-life.
