If you are a knitter, Ravelry.com is about to be your new best friend.
Ravelry is a great resource for information about knitting, patterns (both free and ones that support the artist who wrote it), and general amusements. I am most likely to spend at least an hour (or three) every day browsing everything that this site has to offer.
The latest pattern I found there, "Turn A Square" by Jared Flood, was easy enough to knit more than a few. I knit one for myself in just a few hours, and several more for Warm For Winter. I particularly love the way decreases pair up to turn the top of the hat into a square, while still keeping the rounded head shape.
