"I think the first mud work on paper was River Avon Book of 1979, where I had the idea to make this book with the pages dipped in muddy water. So I got all these sheets, quite big sheets, and after they had been dipped in the muddy water they were cut down and bound into these books. That was the first time I used paper with mud on it."
