Dress up a blank wall in your home with a decorative wall vase. Wall vases may have been around for years, but the wide range of colors, materials and designs makes them one of the chicest modern ways to outfit any home. Because of their variety, wall vases can complement any style or decor, from an elegant dining area to a zany bedroom. Wall vase contents can also be switched easily and frequently, giving any room an instant update. To hang a wall vase also easy to do. Hammer a nail into the wall where you made your mark. Don’t hammer the nail all the way into the wall; you need to leave it hanging out enough to hang the wall vase from it. Fill the vase with whatever you want it to hold. Hang the wall vase from the nail, and step back to examine how it looks. Adjust the vase until it looks straight. You probably won’t be able to use a level to determine if it is straight because it most likely won’t have a straight vertical or horizontal line to follow.
