Embroidering sites....?

I'm trying to learn how to embroider, with strings you use for friendship bracelets, but the books i got are crap and i cant follow what they're showing me. I was wondering if anyone knew of a good site that shows the different stitches step-by-step so i could learn. So far i only know two, and that is cross-stitch and the back-stitch, i want to try and learn more. So any site will be helpful, as long as its designed for new-bes and not people who've been doing it for years.
