This book is a guide to the wool of common and uncommon breeds of sheep: 94 breeds in all. It is divided into four main sections (fine wools, long wools, down wools and other wools). Each section begins with a few pages on general characteristics of wools in that category, typical uses for them, suggestions for washing and processing, and a handy chart comparing the main characteristics of each breed covered. Then each breed is presented seperately, with a photograph of a lock, information on fiber diameter in microns, spinning counts, staple length, fleece weight, etc., followed by a textual description of the wool and its uses. There are also a couple of chapters with good basic information on handspinning, though since anyone who buys this book probably already owns several spinning texts, I wish they would have used the space for photos of sheep or perhaps swatches. Still, anyone tempted to mail order a fleece will find this book useful; it can also help you realize that the sheep common to your area may have interesting wool. No information is given on locating fleeces, but that is understandable. Recommended.
