Determine where in the room a floor vase--or group of vases--would add to the decor. Floor vases can decorate empty corners, hallways, foyers, floor space next to a shelving unit or alcoves near a staircase.
Choose a floor vase that complements your room's decor and color scheme. An intricate, antique vase would look out of place in a contemporary room just as a simple vase might be understated in a highly decorated Victorian room.
Place the vase in the room or corner of your choice. Look at it from all angles of the room to make sure it has the effect you want.
Fill the vase with dried wheat grass or branches, then add dried flowers. The flowers should be proportionate to the size of the vase. For example, large sunflowers would look awkward in a small, slender vase. For smaller flowers in large vases, use a larger quantity. Again, view the arrangement from all angles in the room, and adjust as necessary.
