Moss or fabric looking to creep out an area quickly or other ideas?

[Albert Cicconi]

Looking to hang some spanish moss in an area that needs to be creepier. Any ideas where we can get some fireproof moss or fabric quickly. I have no problem with spraying it with fireproofing either. Its for a pyramid we built but right now it looks too good, it looks like a museum not a haunt...any other ideas to creep it out ?

thanks
Al
