old used window at a flea-market and use it to do this project on, That way you can "Cash and Carry" it with you. lol. Just set it in front of your window, size accordingly measured, or hang it. I did that with a window that had mirror behind it. It was the same sized squares as my window and covered the bottom. I have my privacy...light from the outside on top and it looks wonderful day and night! :)
