Me being a lefty, I thought I wouldn't be able to teach my right-handed daughter to crochet. She was only in about 3rd grade, and she sat across from me and she did great. (I thought I was an excellent teacher, but it turns out she was just really smart) She's now 28, and making afghans.
Cannot believe how long this topic has gone on. Who knew "handedness" would be so facinating.
