The product is called Artscape and it comes in many very attractive designs as well as frosted. It intrigued me because all you need to install this is a spray water bottle and a craft knife.
Here are my front hall windows before, cluttered, dirty and old looking.
I started by clearing away the clutter. Then I cleaned the windows and installed the Artscape. The whole process took me less than an hour and I think they look great now. I'm debating on whether to buy more and put it on the top of the windows as well. I think I will live with it for a while and see how I like it.
I would recommend this to anyone who is looking for a quick update to some old windows. This product also gives you plenty of privacy. Some of the designs are more see through than others. You can purchase this at Home Depot or here is the link to the Artscape that I used at Amazon.
