I've been a member of Ravelry, an online forum of knitters and crocheters.  It's a great way to keep track of your projects, yarn stash, and pattern books.  I use it mostly for noting the yarn and hook size for various projects, and add photos.
Apparently, if I include my blog address in my profile, the various posts show up there, too!  Anyway, I just noticed that, after being on Ravelry for the last 7 years!  So come and be my Ravelry friend!  My nick is Calif-Sharon.  See you online!
