Like Jennifer said, there are quite a few great patterns on this site, so be forewarned - once you get looking, you might not come out of your home for weeks!
Have you tried Ravelry.com? You need to register, but there are TONS of free patterns. Some of my easy favorites are: Limeade Bib by Shelby D., the bibs and cloths by Elaine Fitzpatrick, and if you're not put off by having to do some seaming, I highly recommend Caiden's Skirt by Yumiko Sakurai. If I recommend that last pattern one more time, someone on this site is sure to slap me silly!
But I can't help it - like you, I'm hopelessly addicted to yarn and needles!
