This vintage 1979 hardback knitting book was written by Sarah Don and has 125 pages. The book includes 13 Fair Isle patterns with associated photos and charts as well as a chapter describing the techniques used in these garments. There is also a chapter on the history of Fair Isle knitting (and a great photo of Stewart Thompson wearing his 'Sunday' jumper out in a field (pictured)).
