Lucienne Day

Lucienne Day, who has died aged 93, was the foremost British textile designer of her period. Day's furnishing fabrics, of which the most famous was the Festival of Britain abstract pattern Calyx, hung in every "contemporary" living room in Britain. The reality of "art for the people", dreamed about by the Victorian William Morris, was finally achieved by a female designer in the middle of the 20th century.
Lucienne drew on the English tradition of patterns based on plant forms that went back as far as Morris. She took motifs drawn from nature – flowers, grasses, shoots, the intricate patterns of the landscape – and transformed them into something absolutely new. Part of their success was the implied message of regrowth and optimism for a Britain only just recovering from war.
