oooh, free patterns I've not seen before:

Knit your own gnome!
Fingerless mitt from aran-weight wool (would be nice made of 1824 Wool, I bet)
The Eurosock (knit with Berroco's Europa - I have no idea what that yarn is so I don't know how appropriate it would be for socks).

my favorite one is the gnome. Any pattern that starts off with "take one ball of pretty wool..." gets me interested in it.
