Thinking of doing a walk through haunt this year starting in my garage leading out to my backyard. Kinda want to do a Sanitarium hospital theme inside the garage. not sure what to use for the walls or how to really make it seem as if your in one. I have a Sanitarium sound track to play, tons of bloody props/medical items but other than that idk? Any ideas on props or anything? Also where can you buy those thick clear plastic doorway curtains that are used in like freezer areas?
