Yes, I have officially become a knitting geek. (Sorry, Jen, I know you're clucking your tongue in disapproval, I'm still sticking with it...)
Wanted to mention an adorable yarn store I found while in San Francisco last week, Artfibers, which was an absolute delight to find. I left feeling grumpy and disappointed only because I was on a budget and didn't get to spend more money at this store -- and man, I wanted to. If you're in the area and feel the need for a yarn fix (I just used the term "yarn fix," I just made myself gag a little...), head up a narrow staircase and you'll be more than pleasantly surprised.
