Subtle Patterns hosts high-quality textured patterns for your websites and other design projects. Whether you are looking for a wooden texture or a ruled paper like background for your notepad design, you’ll find them all here in a neat grid layout.
They have a single .zip available with all the pattern images (in .png) or you can head over to Github for downloading the Photoshop pattern file (.pat) that again contains all the patterns.
Should you wish to modify the colors of a pattern, just open the corresponding file in Photoshop, add a new Layer and then apply a different Color under Layer Style -> Blending options.
The patterns are available under a Creative Commons License are thus free to use and download.
