If you know the basics the best way to learn is to just pick a pattern and go. I like the Fearless Knitting Workbook. I found it here. I think you sign up for some 4 books for a $1 each deal, but they have books on everything: knitting, crochet, gardening, cooking, etc. It was harder to pick just 4. Anyways, ravelry is also a great place to find someone to help you if you get stuck on a pattern.
