I love window mirrors, but I don't love their price. I already had a 6-pane window on hand and knew there had to be a way to make my own.
I came across this lovely gem! Rust-Oleum Mirror Effect spray paint. It's somewhat pricey at $8.50 for a 6 oz. can, and I needed 2. But that's not bad when you consider the alternative.
This is the window pane I had lying around. It's oak colored on the other side, which is the side I wanted to be the front. Since you spray the reverse side to create the reflective mirror-like finish, I taped off this dark side.
I sprayed one pane at a time using steady, light coats. It took several coats to get the proper look.
In the end it was about 7 coats! It doesn't have a perfect mirror reflection, but I kinda love its aged look.
