I got my Ravelry invite yesterday and I'm thrilled! I really need a pick-me-up and this was perfect. I only wish I had more time to play around with it!
I learned about Raverly through the MS3 knitalong. Check out www.ravelry.com to see more about it. It's an online community of knitters and crocheters. It's also a way to organize everything you own related to knitting - books, yarn, patterns, etc. I am very inspired by what I see and I can't wait to spend more time learning about it!
