Free Photoshop Texture Toolbox

As far as I can determine, you’re allowed to use all of the textures below for commercial as well as personal projects; however, the creators of some of these textures do ask that you credit them. See each site for the individual rules.
Lost and Taken
Lost and Taken is a blog with free textures and interesting links for the imaging community.
Click on each image below to go to three texture collections represented by these three samples.

Textura
The Textura site contains original textures created entirely from scratch in Photoshop, not from scans of existing objects.
Click on each image below to be taken to the much larger original.

BittBox
BittBox has an extensive collection of Photoshop freebies. The two textures below link to many more.

Vintage Pattern Textures
DeviantArt member ~glass-prism scanned 32 fabric samples for this collection, of which I’ve included just two samples.
