I have a question regarding windows in a haunted house. The space I have to use has a LOT of windows. We have been using black painters plastic but that tends to still let some light in when we have our daytime hours. The other problem I have is with our plastic falling in the middle of the evening. What is the best way to temporarily black out a window in a haunt? I tried not having day time hours but with the short ammount of time we have (we are only open 2-3 days a season) we have to have daytime hours to facilitate our crowd.
