I don't sell textures, I sell jewelry, but people seem to like this one. I originally made it as a Halloween decoration, then put it up on the MP waaaaay back when it was XStreet, before I even had an in-world store.
If you want to use it as wallpaper on your desktop, laptop, phone, whatever, here it is, just right-click and save.
If you use it for any commercial purposes, or I see it turn up in a freebie box, I shall unleash the bats.
If you want a transparent no transfer version for personal use in SL, here it is on the MP:
