Take a look at Moda Bake Shop.
http://www.modabakeshop.com They call patterns "recipes" and you click that and then click quilts and tons of neat free patterns come up. I have used some to teach with at my guild... Flights of Nature, Avignon Picnic, Sweet Menagerie. I am sure you'll find a few you like.
Try Pinterest. Tons of pics of quilts there and they will have the link underneath.
Also just Google "Free Easy Quilt Patterns" and see what happens.
