First published in 1981, this book by Sheila McGregor is considered a staple for stranded knitters. It is chockablock with charted Fair Isle patterns. Of course, there is the chapter on the history of FI knitting along with some B&W photos and a few colour ones. I like the sections on design, techniques and colour. Yup, she talks about steeks!
I recommend this book for the FI enthusiast - buy it while it's still available.
