Here is another design tip when trying to make a ceiling look higher. Add a shape to the bottom of the cornice. By adding movement to the bottom of the cornice it can trick the eye into moving up and down so the eye does not stop at the longest point of the cornice.
You could also accomplish extra height with drapery panels and a decorative rod. Notice the difference when you mount the drapery rod at the top of the window or when you mount the rod under the crown molding or near the ceiling.
We recommend giving every room that extra lift! Would you like to see how new window treatments could change your room? As part of our service we create renderings to help our clients visualize how new window treatments will look on their windows.
