I can think of two alternatives right now in addition to the shower curtains. IKEA has such a large selection of window and shower curtains. Some as cheap as $19.99. They may work. Or if Seattle has a fashion district where they sell textiles like in the fashion district in LA. You are in Seattle right? I just went to the fashion district in LA earlier this week and shot some amazing fabric that I will use as backdrops. Everything I bought ranged from $2.50-$4.00 a yard by 60 inches. I buy 5 yards. So yeah, hope that helps.
