This book is amazing. Amazing! It tells you about all different types of fibres, where they come from, how they are harvested or created, and how you can expect them to re/act when knit.
My brother gave it to me for Christmas/my birthday. It was on my wishlist, and I'm very happy to have it! The book is well-written and really informative. Not to mention that it really feeds into my desire for an alpaca farm and angora bunnies.. I was reading this on the train home to Montreal after flying back from Cuba and was actually giggling aloud. My seatmate kept peering at my book, presumably wondering how knitting could be so funny.
I haven't checked out all the patterns, but they seem pretty nice. Nothing jumped out at me, but I'm sure I will knit something. The ruffled scarf is quite nice.
I highly recommend this book. It is a great resource.
