This dark blue piece of fabric has a lovely sun bleached pattern. It looks almost like an X-Ray, and would make an excellent psychedelic background for festivals, theatre, or your living room. It measures about 10 feet, 7 inches by 5 feet, one inch. I didn't do a burn test, but I am almost certain that it is polyester. I am tossing in this bag of 20 large diameter glue sticks because hot glue is the best thing ever. Upon your order, I will launder and fold the fabric before shipping.
