In late 19th century Cornwall hand-knitting was a vital cottage industry and coastal villages developed their own distinctive patterns and names for the traditional navy blue guernsey or knit-frock. Contract-knitting - the occupation of many Cornish women - had died out by the 1920s and was almost forgotten until author Mary Wright started asking old people what they remembered of it. Her research has resulted in a remarkable picture of social history. Cornish Guernseys & Knit-frocks includes many delightful contemporary photographs, and detailed instructions and charts show how to knit a Cornish guernsey incorporating one of thirty local patterns.
