A really awesome window treatment can transform any room. One of the most important components of your window treatment is the drapery hardware responsible for hanging, displaying or drawing the curtains or fabric. The primary function of curtain rods is supporting curtains to cover your windows, but these furnishings can also add detail to your room. Decorative curtain rods should relate to the style of the room. The best curtain rods to choose depend on the types of curtains you plan to hang.
