Looking for a quick, simple, way to add some window treatments to a bedroom and save money at the same time? Look no further than the bedding section. No, don't buy the curtains. Buy the flat sheets. One flat sheet will make a set of panels for an average bedroom window. Turn the sheet over, on the back side, make a slit at each side of the top hem. Push the curtain rod through the first slit until it comes out the other end. Hang the curtain rod back up. Continue to the next window. Bam! Your windows covered for a fraction of the cost of window treatment panels.
