Haunted house wallpapers and fabrics

Though it doesn't carry the Haunted Mansion's "Demon" wallpaper, Timorous Beasties can provide you with rolls of some pretty creepy wall-coverings. My favorite is this iguana wallpaper.
Also be sure to check out their "Devil Damask" fabric. It's subtle enough that most people wont notice Satan peeking out through the lace, but still noticible enough that all your haunt friends will envy you.
