Subtle patterns

SubtlePatterns offers nearly 400 tillable patterns for your web designs. These patterns, as the name implies, are subtle, clean and will work with virtually any design style. You can download them for free, or use the $12 Photoshop plug-in which puts them right into your workflow.

The cool thing about this site is that you can preview each pattern as a page background simply by hovering over each pattern and clicking the preview button.
