How to Make Blackout Curtains Out of Existing Drapes
- 1
Make a temporary blackout curtain when light needs to be blocked for a day or two. Use an emergency blanket made of aluminized polyester to line the drapes. This is a shiny, lightweight fabric that looks like foil. A typical emergency blanket is about 52 inches by 82 inches. It can be taped or pinned directly to the back of the drapes and removed when no longer needed. These emergency blankets, folded to fit into a pocket, are available in auto and sporting goods departments. - 2
Replace an existing drapery liner with blackout lining. If the existing liner is on a separate rod from the drapery, measure the existing liner as a guide. Purchase a blackout liner replacement at a curtain or department store. Most blackout liners are white or ivory and fit smoothly on the drapery lining rod. - 3). Choose an integral liner such as a Roc-Lon Blackout Drapery Liner. These inexpensive liners are used in hotels and hospitals to block outside light. Measure the existing drapes. The integral liner comes in several sizes and in one or two panel styles. These ready-made liners fit almost all existing curtains or drapes, require no tools, and often come with hooks for easy installation.

Look for lining features such as TLC indicating Total Light Control. Some two-panel linings offer magnetic closures. These are magnetic strips down the center of the linings to keep the two panels together and avoid light leakage. If total light control is not needed, a dim out lining is usually lighter in weight and is rated about 80 percent light blockage. - 5
Choose a drapery lining to fully cover the window. It may be tempting to select a shorter lining to save money, but the lining should be matched to the existing drape size. Some blackout linings come in colors. Remember that the color will be visible through the window and should coordinate with the other windows when viewed from the street. A good lining will last for years, improving sleep, study, computer use and TV watching.
