I am an avid crocheter now for 6 years; I was a knitter before that, since age 5 (my mother and both grandmothers are knitters). I taught myself with the help of online sources. Below are the list of some very helpful sites for learning to crochet.
I actually learned to crochet from my schoolteacher but I do know that most handcraft shops have books on the subject which are quite easy to teach yourself from.
Does your mother crochet? If you are used to doing things backwards she might be able to tech you. Like you, I'm right-handed but my mother is left-handed and when she tried to teach me to crochet I simply couldn't get it because she did it left-handedly. She taught me to knit however because she does that right-handedly.
No, I haven't heard of a tutorial video for this sort of thing before. Is it good? I'm trying to teach my twelve-year-old sister to crochet but it's not catching on (I've been trying to teach her on and off for the past five years), so do you think this video might help?
Having said that, I'd like to say to all you homeschooling mums out there that crocheting is a very good thing to teach children. Mum tried to teach me to knit when I was five or six but it was just too complicated, however I picked up crocheting quite easily at that age because you have less stitches on the needle/hook at any one time.
