More of a well presented survey,
This review is from: The Complete Guide to Spinning Yarn: Techniques, Projects, and Recipes (Paperback)
This book is want everyone needs when looking up terms and techniques.
If you need in-depth explanations then it is time to buy a book on the particular topic. I find the DVD's from Interweave to be much better than any book.
The strength of this book is that no matter how yarn savvy one me be there is always something new or old that is missing from one's repertoire.
For anyone that really has no intention of spinning or dying, you are still bound to run across the occasional term in your reading. Do not gloss over the term look it up in this book and add to your reading pleasure.
If you do not want anyone touching your Niddy noddy you better know where it is.
The pictures and diagrams are worth the purchase alone.
