Knitters and crocheters have their own FB. It's called "ravelry" and it's free to join. You get your own space where you can display what you've created, have friends and groups, send and receive messages, choose favorites and build a queue of items you want to make. There's an extensive library of patterns available, many of them free. I have fallen in love with this website. It's a wiki-thing and full of amazing features. It's the most efficient social networking site I've ever been on. The pattern search has a sophisticated filter/tag system that is so easy to use. I highly recommend ravelry.
