The Vault in Asheville, and dutifully (though with a bit of whining) threw myself into bolts upon bolts of fabric. Thankfully, I spent most of my time at the machine and not pounding grommets into yards of hems. The end result wasn't perfect, but it transformed the cinder block walls and achieved it's goal of softening the room and keeping the sound from bouncing around.
Then, wouldn't you know, after a few years, the fire marshal decided they were a fire hazard. (?!?) So, down they came. The room looks very cool now, with black leather wrap around couches which certainly provide a lot more seating for conversation with friends.
But what to do with all that fabric? I certainly couldn't let it all go to waste... So...
I should add that I made the costume using this technique found in Wendi Gratz's fantastic sewer/crafter's blog.
