I want to make a walk-thru mirror for my haunt this year. My idea is to take clear strip door material (fear flaps) and add mirrored mylar to the back of it essentially creating a flexible mirror that people can walk through. Not sure how I'm going to adhere the mylar to the flaps. I thought about spray glue, but I'll have to test it out. Anyone know why this won't work, or have a better idea? I thought I'd toss it out here before I set to experimenting.
