I've scanned my latest batch of textures. They are pretty understated, but maybe that's what a few folks are looking for.
My rules are: You can use these for anything you want, including commercial endeavors. It would be nice if you were to link back to this deviation so that others can use the textures as well, but I'm not at all strict about attribution.
The only thing you can't do is sell the textures exactly as they are. Otherwise, go nuts :3
By the way, these are just jpgs. You open them up like you would any other file.
