Banners with Patterns

After reaching the required level to upload a banner, I was surprised to discover the size of it: 1680x153. I tried thousands of images, but none of them had a good feeling about it in that particular size. Then I thought that a pattern like the ones offered by Snapzu might be a better idea. I found some really cool free ones here:

this on going project compiles patterns shared by the most talented designers out there for you to use freely in your designs.

Edit: It would be really cool if people posted other places where we could find this kind of free patterns.
