My mother, Helen Hoyte, who has died aged 100, was an expert on the shawl-making industry of Norwich, and wrote a book on the subject that included her own beautiful illustrations.
Helen first became interested in Norwich shawls when, after retiring from art teaching, she met Pamela Clabburn, whose family had been involved in shawl-making in Norfolk since the 19th century. With Pamela and others, in 1989 she co-founded the Costume and Textile Association to promote interest in the heritage of Norwich and Norfolk, and to encourage research into its various facets.
