Trends seem to run in cycles, and vaulted ceilings are back.  Vaulted ceilings, also known as cathedral ceilings, can make a room feel much larger than it actually because of the open vertical space.  But all of this open space can also be hard to dress.  Furnishings can get lost in a vacuous space, and while the room may feel large, it may also end up feeling impersonal.  So it is a challenge to make the room feel intimate and at the same time, larger than life.  

Tying It All Together
 
It is easy to get a room off balance when decorating a room with a vaulted ceiling.  It is important to balance what is happening in the lower half of the room with what is going on in the top half of the room.  It is all too easy to have the open ceiling space simply minimize everything in the room.  One way to tie the two halves of the room together is to use wallpaper with a coordinating border, and then repeat elements of them throughout the entire space.  By echoing elements in each half of the space you visually tie the two spaces together, and, by doing this, the space no longer feels vacuous. 

Tall Walls Need Artwork

Generally with vaulted ceilings you end up with giant wall spaces that you need to fill.  You can certainly find a huge piece of artwork to fill the space, or you can repeat smaller elements to fill the wall.  For example, by hanging a collection of mirrors or pictures with the same color frames, you create a large focal point for the room from a lot of little elements that all relate to each other.  Sometimes a large wall comes in handy, as in a family room where you want to hang a huge plasma screen television.  Just remember with tall walls, you want to use as much vertical height in your accessories and wall art as you possibly can.
 
Dress the Windows

When you are designing your window surrounds for a room with a vaulted ceiling, you want to consider the configuration of your windows.  On large walls you may want to consider many windows as one, especially if the windows relate to each other in some way.  For example, if you have three stacked square windows, it would be much more dramatic to hang curtains from ceiling to floor and treat them as a single window than it would be to hang curtains on each window opening.  Then if you need privacy or want to block bright light, you can add a shade to each window matching the wall color, and you will have functional window coverings without sacrificing the drama created by the drapes.

Large Scale
 
As you select furniture for you space remember that the open ceiling makes the room seem even larger than its dimensions would indicate.  So you want to make sure that you pay attention to the scale of the furniture that you are putting into the room.  This type of room is perfect for oversized and overstuffed.  So when you choose the scale of your room, make sure that the size of the furniture, size of the wallpaper patterns and upholstery patterns, size of the wall hangings and size of the accessories in the room are all in the same range.
