(Can you tell I'm searching out all the newbie knitting threads?)
Anyway, in addition to knitting help dot com, nothing beats finding your local yarn store and sitting with the ladies there. I went in today, having just bought my materials and yarn yesterday. As soon as I walked in they said "Have a seat". Next to me was a girl knitting a little bunny, and soon another young woman came in with a bag of her project and said "the kids got into it." So out came her sweater, and a bunch of tangled yarn (I think she was knitting with 2 pieces of yarn at once.) Someone started helping her untangle and re-roll. As she re-rolled, she watched what I was doing and offered tips, etc. This wasn't even a class, just the regular drop in help.
the on line stuff is fine to learn, but I think you also need someone you can show your stuff to, so they can figure out where you went wrong, even if you can't.
