Grey Wallpaper

So when placed on a large wall, this texture stretches out enormous. Problem is, it can't be resized and tiled because it has a bizarre border on all sides. This border is visible along the top edge of all walls as well, even the small half walls.
Can't use it as-is because the marks in it look like beef jerky, they're the size of my avi's arm. Thank the gods this was only L$1.
