Here... um... have this random old thing to play with.
(It's a .psd file, sorry for the tiny crappy preview - have some
bigger examples.)
Might as well upload it for others to use, rather than just abandoning it.
It's a greyscale, or base, or whatever you call it. Add your own design/markings on top. Yaaaay.
It comes with the basic (editable) background stuff too. So if you're
really lazy, it can be an instant reference sheet.

You can also use this for adoptables, and sell them for money or points. Do whatever you want. I don't mind at all.
I hope the price isn't too much. Sorry. Just half a dollar? ^^'
Since it did kinda take me a while to put together... and maybe it'll deter some potential lazy thieves? Ehh.
(I often see people charging 100+, even 1000+ points for linearts/bases, which I find horribly greedy... but hey...)You can remove the credit from the image, if you'll give credit elsewhere (in description for example).
Oh, and I made the texture myself... use it for other things if you like, but credit would be nice.
Well, uh, go crazy! Woo! I hope some people find it fun/useful.

(The text layer was incompatible with PSE 10, but I made a new text layer in the same format.)
