Hello all. I have read and seen past threads on mirror blind. The concept has me really intrigued to learn more. It would sure have its uses in many places where I hunt. I have watched the videos on youtube of the guy building his own. I love the idea of that other than one thing. The price of a 4x8 sheet of 1/4in plexiglass is $190 in my area. Does anyone have any experience building one of these and using something cheaper than plexiglass? Any ideas/suggestions would be appreciated. Basically just need a materal that is clear and that the tint will stick to. Thanks
