Two really great books that I am reading are The Knitter's Book of Wool and The Fleece & Fiber Sourcebook. If you need to know more about sheep/wool/fiber they are very helpful. I saw that one of the authors on the The Fleece and Fiber Sourcebook will be at the Kentucky Sheep and Fiber Festival this May. That is where I purchased my alpaca fiber a few years ago. I would love to go again someday.
