I joined Ravelry months and months ago. (I just went and looked. January 12th! OMG) So far, out of all the brilliant features that are offered, I have used.... none.
Every time I log on, I think THIS time I'm going to actually DO something - use the notebook, start a queue, list a project, post a damn picture.
I start looking at pretty pictures. They lead me to other pretty pictures, and even more pretty pictures. Whatever time I could have spared to accomplish anything gets sucked up by rubber-necking.
Robin Gallimore's gorgeous sock patterns
what everyone else has been doing with the Baby Surprise Jacket
Cat Bordhi's patterns
Ooops. Sorry. Wandered off. While looking for examples, I sort of lost track of what I was doing.
Like I was saying...
I hear they have forums, too.
