Decorating Room Ideas #1 Turn any boring ceiling into a beautiful one like this one. All it took was a few hours of gluing polystyrene ceiling tiles onto a a regular popcorn ceiling. Yes, it's styrofoam. Its very inexpensive and easy to work with. The great part is that you dont need to hire anyone to do it for you. Like I said they are styrofoam so they dont weigh much at all. Dont even get me started on how easy it is to cut! If your looking to cover up that old water stain then these ceiling tiles will do the trick just glue and apply. Its that easy! Trust me, you do not want to spend three times as much getting your old popcorn removed and then reapplying it. Why would you? They are not just for decorating your ceiling but also great to add some home value and beauty! Give it a try.
