I got a surprise package from my in-laws yesterday! I usually dislike surprises, but this was a really good one. It's The Joy of Knitting, by Lisa R Myers. She combines academic analysis of various knitting-related topics, knitting advice, and patterns. I'm only a little bit into the book, but it's so fun already!
The book is even autographed by the author, in 2003. My father-in-law found the book in a used-book store while traveling. I guess my used-book and knitting obsessions have been broadcast enough that other people look for used-knitting books for me!
