In search of a few specific items...

Does anyone on my f-list in the area:
a) know of a place to get large quantities of sheer plastic cheap? Like, shower curtain material, enough for two or three curtains?
b) have a white claw-footed bathtub (preferably near a window) that they wouldn't mind me commandeering for a few hours during a photo shoot on thursday? Baked goods/jewelry would be offered as compensation.

K thx.
