:-) Finally got my Ravelry invite, and it's coooooool (username Scientknits).
I actually got it almost a week ago, and I haven't succumbed to the vortex just yet. I haven't had that much time to concentrate on digging out the best stash photos, or photos of my completed projects, but I'm starting.
If you haven't checked it out, and you're a groups-type of person, you definitely should give it a look. My favourite feature is the ability to search patterns and see what other people have done with the projects I'm contemplating. I don't have complete confidence in my yarn choices yet, but it's comforting to see that other people have used trekking for Pomatomus, for example. I'm still sitting on the fence about starting a sweater, but I can look up what others have done with Mariah, Samus, or Josephine.
It's an excellent resource, and it gets my hearty approval!
