How to make haunted house walls?
How to make the walls: Do you have a patio you can work with? If so, just hang the black visqueen from the roofline. If not, the cheapest & easiest solution (really!) would be to build your haunted house something like a lean to, running the entire length of the house. The lean to is a structure that is attached to a wire (or in your case, the roof) and would stretch to some point along the ground like this \. The visqueen can be secured with tent stakes, and would give you at least 8-10 feet of width. It can be as long as the length of your house, or shortened to 20 feet in length. For a daytime party, use visqueen flaps to cover the entrance and the exit. I used this configuration some years ago to create a haunted house along the side of my barn, and the end result looked something like a cave.
