Using a double curtain rod can add a decorative touch to a room and versatility to window treatments--allowing a combination of sheer and opaque panels to be used. However, many homeowners and renters have a single curtain rod, and do not know how to switch them to decorative double rods. Converting the window treatment is a simple process and requires only a conversion kit and about a half an hour.
Purchase a curtain rod conversion kit. They can be found online, and in most retail and drapery stores. Kits typically contain the required brackets needed for hanging, hardware and a plain curtain rod. Choose a color and style that are similar to the original single curtain rod being used.
Remove the existing curtain and curtain rod from the bracket. Place in a location where the curtains will not become wrinkled, accidentally stained, damaged or become covered with pet fur.
Carefully remove the existing brackets and hardware. If the wall is damaged from the process, repair the area with wall-patching compound, sand and repaint. If the area is severely damaged, and will not hold the new brackets and hardware, repair the area and place the new hardware in a slightly different location--at least 2 inches above, below or to the inside or outside of the original location.
Attach the hardware and brackets from the curtain kit to the wall, using a level to ensure that the curtain rod will be even when installed. Follow the instructions included with the kit for the exact installation procedure.
Place the inside curtain (the one closest to the window) on the plain curtain rod. If the curtain is wrinkled, place the draperies in the drier on medium heat with a wet washcloth. Put the rod on the closest bracket to the window.
Place the second curtain on the original (or decorative) curtain rod. Hang curtains in place on the bracket closest to you. Check visually and with a level to ensure the conversion from a single curtain rod to a double is even.
