Hi Kristel, Welcome! I was a self taught quilter a long time ago; I had bought a book at the time but did not ever follow all the instructions. :)
A few years ago I had more time on my hands and started quilting again. I got a lot of help at
http://quilting.about.com. Whenever I needed instruction or a refresher on a particular step, that site had the answer! Step by step instructions are provided with pictures, for example on how to make and attach binding, or how to make a mitered border. I even got my first few block patterns there.
Now, when I want to learn a new technique I usually buy a book about it, usually on Amazon, or buy a pattern at the quilt store or download a pattern from the internet. I have learned a lot on this board too. I acquired my love of paper piecing here!
As for machines, they are like motorcycles. If you own a basic one, just use that for now. As your skills increase and you find out what you really want to do, then you can shop around for something more sophisticated. That way hopefully you will only have to buy your dream machine once. I hope this information is helpful. Happy quilting!
