Made from other people's textures...do I keep track of whose? No, I'm a texture hoarder.
But they're not mine. Suffice it to say this looks very little like any of the originals. They're from all over the place, but if you spot your own texture in one of mine, I'll double-check it and credit you.
Use it however you'd like, just don't repackage or claim it's yours. I'd love to see what you do with it, though.
