I didn't think I would find a lot to love about this book. Right now, I'm not interested in raising silkworms. I'm also not into dyeing silk (although I hear it's very easy).
But, there was still a lot of great information for me to enjoy.
In particular, there was a really interesting article about different types of silk from around the world. It turns out that many different regions (South America, Africa, China) have native species of moth that create silk cocoons.
On a practical note, I especially liked the discussion on different preparations of silk. (Silk usually comes in hankies, tops or bricks, or can be blended with other fibers.)
I actually used advice from the book right away. A friend of mine gave me 1 oz. of silk/cashmere top for Late Christmas (my knitting group celebrates Christmas during the summer, so that we can concentrate "real" Christmas knitting on family). Reading this book finally gave me the courage to spin it up this week. I spun it over the fold, since that makes the long, slippery fibers of silk easier to handle.
There was also a great piece from Judith MacKenzie about spinning plump singles with silk blends. That, alone, was worth the price of the book, to me.
Plus, the book has a 30-day money-back guarantee. So, you have nothing to lose, if you don't like it.
Overall, an interesting ebook for anyone who is into history, silk, and spinning.
