I, as usual, have been browsing Swap-Bot which, while it does leave some things to be desired, has quite a few neat swaps. A lot of the swaps are Artist Trading Card (ATC) swaps, which I tried, and didn't really like, although I had fun making "stained glass" ATCs on cellophane.
I'd like to give a little shout-out to some recent upstream pals: Morgsarah, thankyouthankyouthankyou for all the fab spinning things, Ms. Pryor, I love those handwarmers (and your calligraphy) (and that stamp).
The swap I'm talking about now is a knitting kit swap. I really like the idea of this, because it's very personalized, and you could come up with pretty much anything (including using your own patterns or handspun yarn).
There's still a lot of time to sign up (hint hint), and the swaps are sent out in late November (just in time to maybe make a pair of socks or mittens.
