I have had insane luck with used book stores; maybe good karma for donating Knitting Nature to the library? It's not on the shelves yet, but I have high hopes... They probably just need to get it plastic-wrapped.
I dropped into the defunct Walden Books down the street and, bless my stars, found a knitting book! The Knitting Goddess by Deborah Bergman for $5. It's a very basic technique book filled with fiber-related myths. It's a cute book and has great art and stories, but I've read so many books by women who've found knitting while on a great spiritual journey. I know it's little of me, but I get a little bitter hearing about women who have time to find themselves while I have to work. Still, totally worth the fiver.
At Acres of Books the knitting book cupboard has been bare for weeks. A little digging around unearthed Patterns for Guernseys, Jerseys, & Arans by Gladys Thompson and Complete Guide to Modern Knitting and Crocheting by Alice Carol. I felt like I needed a second guernsey book, and the Guide has a treasury of vintage patterns. I've already found an argyle sweater that I'd like to wrap my needles around.
So go hit your local used book stores, thar be treasure afoot!
