Similarly, window drapery can be hung from the ceiling instead of on the wall just above the window. Hardware for most window treatments is designed to be flexible. So try turning the bracket up and installing it on the ceiling. The length and vertical lines of the drape will make the ceiling feel higher and the room larger.
To maximize limited floor space — especially because the bed typically takes up much of this valuable real estate — incorporate flexible furniture that folds up to the wall. You might try a foldout desk that doubles as a makeup table. A wall-mounted pullout shoe organizer in the closet can free up space on the closet floor for a small chest of drawers, adding needed storage.
Storage furniture, such as bedside tables with drawers or even small dressers, can also be affixed to the wall, leaving space beneath to store shoes or stylish baskets stashed with necessities.
Drapes and shades are a fundamental element to make a space feel warm, and I also like to use rugs to make the space feel softer. There should always be an inviting area to sit, read, and relax.
