"Broken" Windows Tutorial. Use frosted contact paper and cut it apart to look like fractured glass. Apply it to the inside or outside of the window. The semi-transparent frosted contact paper takes on the appearance of the "glass" while the actual glass pane (which is transparent) disapears.
I am sharing these photos because I spent so much time researching options for our basement floor and wish I could have found more before/after photos. We decided to try H&C Semi-Transparent Concrete Stain in Expresso. My dad applied two coats of stain and two coats of the top sealer. I love the results!
