The book opens with a section about the care and analysis of wool. If you are planning on choosing, preparing, cleaning, and managing the characteristics of the fleese you will spin, this is an invaluable resource.
Within this section, you can learn about genetic factors affecting the color of fleece, storage, staple lengths, crimp patterns, and a whole lot about specific breeds of sheep. Eighteen breeds and two types of fiber preparation are discussed in detail.
When I say "detail," I'm not joking around.
For each of the breeds, staple length, staple shape, crimp pattern, fibre size, colour, lustre, bulk, cleanliness, soundness, location of source, suggestion for spinning, and suggested end uses are all listed. These are like baseball cards for sheep breeds.
Section Three: Yarn Design covers the major forms of drafting, plus fiber preparation like carding and combing. Anne even notes which breeds might be best used for each spinning method, which is very nice.
The last section of the book is a series of both woven and knitted projects, including machine knitting and a project involving felting yarn while it is still in the skein.
Overall, a great book. It's a lot to digest for a beginner like me, but I'm happy that the resource is there when I'm ready to move on from my Corriedale fixation (which is the first breed described, by the way.)
