I once used several bolts to make floor to ceiling curtains for my screened in porch. I had VERY nosy crabby neighbors who had nothing better than to do than constantly spy on me (with binoculars, even!). I used the muslin because it was cheap. Anytime I was out on the back porch I could pull the curtains for privacy.
The crabby neighbors finally moved (we lived next to each other for 15 years) and the "curtain" became a couch cover to protect my upholstery from my 2 year old.
