This is complete course in fair isle knitting. After getting intimate with the authors, the book dives into a very thorough study of the intricacies of knitting in the two handed, totally circular, steeks, et al. method kept alive in fair isle lore. I enjoyed the way a collection of colorways, a collection of fabric chart patterns, and a collection of a range of sweater sizes and styles are all intertwined into this fascinating text. Full color.
