Everyone needs a little bit of sunlight in a room, but it's important to be able to block out light, especially when you are sleeping. For this purpose, nothing beats blackout drapes. Hanging blackout drapes over your windows gives you the option of absolute darkness when you need it most. Blackout drapes can also help to muffle exterior noise, so you remain undisturbed by the goings-on outside of your room. You can buy pre-sewn blackout drapes, or you can make your own out of blackout curtain material. It is relatively simple to hang blackout drapes to eliminate light, but there are a few things to consider when deciding how they will be hung.
Measure the length of the area that you want to be covered by the blackout curtain. If you are really trying to eliminate all light entering through your windows, hang the drapes several inches above the top of the window frame and a few inches to the left or right of either side. This is most effective when it comes to blocking light.
Mark the area on the wall where you plan to hang the curtain rod brackets.
Install the curtain rod brackets onto the wall using the included hardware.
Slide the blackout curtains onto the rod using either tabs, drapery hooks or the "sleeve" that is standard on a lot of pre-sewn curtains.
Place the curtain rod with the blackout curtains on it into the brackets you have mounted on the wall.
Slide the curtains around on the rod until you find the perfect balance to provide complete coverage from the external light.
