Totoro Baby Bonnet
Awhile back, I randomly ran into a Totoro Baby Bonnet pattern via Flickr. I don't know any amine-appreciating babies, but I do want to convert this to an adult hat. Another thing to add to my ever expanding "to-do" list.
That same site, Hello Yarn, also has some other great free patterns worth checking out, particularly if you're looking for a nice cable project, skulls, or gorgeous double-color knitting. My other favorites include the Besotted Scarf, We Call Them Pirates Hat, and One Baaad Poncho. There are also some gorgeous handspun and hand-dyed yarns for sale, though I'm too poor to do anything but drool for now.
