Even though basements may not have windows, you can create the illusion using drapes

When homeowners decide to renovate their basements and turn them into more functional, liveable spaces, they often greatly increase the amount of useable square-footage in their house. By doing this, they are opening up the potential for any number of possible uses, from a family den, a home office or a game room.

However, because basements are subterranean, window treatments don't generally come into consideration with underground interior design. This can be problematic, as something may feel missing in a large room without any windows. Curtains are a big part of interior design that dictates a large portion of a room's overall aesthetic. However, you can use window treatments in basements to add to the design scheme by creating the illusion of windows when there aren't any there.

By choosing long, lush drapery and attractive window treatment accessories, you can make it seem like they are hiding a window that simply doesn't exist. You won't be fooling people, as they know coming down the stairs that they are entering the underbelly of the house, but you will be given the opportunity to decorate the room as you would any space above ground.

By hanging a long velvet blackout drape from a rod and tying it in the center just below where a window sill would generally be placed, the look is achieved. This will make it easier to decorate the rest of the room, as you won't have to overcompensate with wall decor to fill the void left by the absent windows. This will let you take advantage of vibrant hues or playful patterns to make the look you want come to life in your interior space.
