I know of a wonderful website to teach absolute beginners how to use a computer mouse, but if you don't know anything about the internet how would you find it?
There are many, many sites that can teach you to knit, but if you don't know the right words, how do you find them. And judge how good they are?
Knitting help is the best site I have seen, basics to advanced, written guides, pictures and video, so it suits different learning styles.
One of the most interesting places to take a class is Olds, I am teaching there this summer. It's a summer camp for grownups.
