Like most knitters, I’m a sucker for expensive fibers, and while I usually keep my pocketbook in check, it can be tempting to fall for a new-to-me variety. Even if I don’t really know what kind of creature produced the fiber, if it’s soft and doesn’t set off my allergies, it can be hard to resist. This book, though, is a great resource for knowing what you’re getting. From sheep to rabbits to camels to yaks, it’s all here. My post at CPL has more on this one.
