OK here's a crazy post for every one.My GF wants to have a mirror on the back wall and use it as the wall.As far as I know you have to have a existing wall and then you mount it to the wall.Mirrors are to fragile to use as a wall and someone could break in pretty easy.Could we use sliding windows and put a film to make it into a mirror?We were going to make a back room and enclose the shop later down the road but for now the back wall needs to provide security for shop.Anybody know of a good store that deals with custom mirrors or even some one with interior design experience.I could try to explain this subject better but I will see what kind of replys I get and then go from there.I want this shop house to look good and have GF happy too but not looking to go broke with this mirror thing.
