In 1965 Rena moved into a cottage at Tarrant Monkton, near Blandford Forum, where there was sufficient space to install a commercial printing press. Her book production began to flourish. She established her relationships with the National Trust, Salisbury Cathedral and other clients, and by 1970 she was making enough money from the books to give up teaching and concentrate on book production. However, she still found time to produce paintings, pastels and drawings of England and abroad. The paintings from France show her particular interest in Romanesque architecture and sculpture. During this period she produced many of her most successful books and mastered her illustrative technique, exemplified by three large-format books on Dorset and the books about Cornwall, starting with Cotehele in 1973.
