Five textures for you for free use (commercial or non-commercial) - no credit needed.
I took these photos and adaped them so that you can set them as tiled patterns. To do that, just select the tile you need in Photoshop with the rectangular marquee tool and then choose Edit > Define Pattern.
This way you can edit the textures as you like before you set them as pattern.
Of course I am curious about what you'll do with these textures so I'd be happy to receive links to your creations. I also appreciate your faves and comments very much and I'm open to your suggestions and critique.
