Granny Squares

Well, I'm sad to say that my granny square afhgan isn't going as fast as I was hoping. I've only got about 8 so far and I need 20. I'm having trouble crochet lately. My hand starts hurting after only one square! I know it's because of the way I'm holding the yarn with my left hand. I kind of curl my pointer finger up to hold it and it gets cramped quickly! I'll figure it out eventually. I can knit so much better than I can crochet, which is funny because I've been crocheting a lot longer than I've been knitting.
