A few months ago I joined Ravelry, and it has changed my knitting world. I can search for patterns and see what yarns people have used and how it looks on various body shapes. I can look up a particular yarn and see what people have done with it. And last but not least, I can record my own projects and stash.
To Jeff, late at night: But if I stay up a little bit longer, I can tick off another 5% on this project!
