William Morris first produced machine-made carpets in the 1870's but quickly opted for hand-knotting. When discussing carpets he states "the designs should always be very elementary in form and suggestive merely of forms of leafage, flowers, beasts and birds etc", (Oliver Fairclough and Emmeline Leary, Textiles by William Morris & Morris & Co 1861-1940, London, 1981, p.50).
