If you’re looking for a subtle, clean background image for your web site, look no further than SubtlePatterns.com .
I am working through a tutorial on CodeSchool via Pluralsight and in the video, the instructor put up a note about this site. I’ve used it before, but I’d forgotten about it. Subtle Patterns is chocked full of very modern, clean and dare I say, subtle patterns you can download for FREE!
There is even an extension you can purchase to feed all the available patterns into Photoshop automatically.
Check out the site for a vast array of inspiration.
