We use Scene Setters to cover the front and side of the garage and our entire front porch. Last year, DH taped the Scene Setter to weed barrier cloth with clear duct tape, then put grommets in the top to hang it on hooks on the walls- held up to the big October rainstorms we normally get (lots of wind, lots of rain). They're acceptable during the day, but at night they look great, as the various wrinkles and folds add more texture to the stone pattern. After Halloween, we put them in the garage until dry, then roll and fold to store til next year. Eventually we'd like a more realistic look, but these work for now.
The material is best used indoors against smooth walls- there you can get a tight fit into the corners and a smooth appearance.
