Hello! I just taught myself a few months ago. I started out by going to my local bookstore and buying "Stitch and Bitch." This is a book with a sense of humor that tells you everything you need to know about yarn, needles, etc. It also has three beginning projects with detailed instructions that build on one another. (My only gripe about this book is that I wish those projects continued evolving. Instead she moves you right on to patterns after those three and you're on your own.)
Now the actual knitting process, like casting on, knit and purl, etc. - I couldn't pick up from the illustrations. Instead I went to youtube and just watched videos of whatever I was trying to do and that's how I learned.
I bought a second "how to knit" book called "Chicks with Sticks" because it had a beginning sweater shell in it that had detailed instructions. It's a beautiful book. I really liked the felted clutch pattern which SnB didn't have.
There are a lot of good "how to" videos on this website too - - but the one's I've watched so far have no sound. I like the youtube videos because you can hear them talking about what they're doing. They'll give you tips as they knit, like "be careful not to..." etc.
If I did it, so can you!! Happy knitting!
