A buddy of mine bought a bunch of moving blankets off ebay and hung them all around his practice area. I believe he found a way to install a bunch of brass eyelets in the blankets and then hung them using heavy-duty hooks. I know it was a pain to put in the eyelets because he bitched about it for weeks afterward. You have to punch out the proper-sized hole in the blanket first, then you place the eyelet halves and swage them with a special tool. A lot of work, but once they're in, they ain't goin' anywhere.
