Wow. I've only been spinning for a year, but I've looked through almost every spinning book there is, and this one is definitely one of the best. It covers drafting and spinning techniques in great detail, describes every spinning fiber you can think of (and some you wouldn't have imagined!), and the plying and design sections are excellent. It is very well organized and illustrated, and her writing style is clear and occasionally highly entertaining. I'm beyond the beginning stage of spinning, and this book has provided me with all the information I need to take my spinning to the next level. Highly recommended.
