  An ordinary room can be transformed into an extraordinary one when decorative crown moulding is used. Crown moulding comes in different widths and styles and can be used for a variety of purposes.
  
  

Where the Ceiling and Walls Meet

• If your ceilings are eight feet tall, stick with two to four inch moulding. A nine foot ceiling can accommodate moulding that is four to five inches in width. The higher your ceilings the wider your moulding can be. If you have really high ceilings (10 to 13 feet) your moulding can be as wide as two feet. A moulding dresses up a room and gives it that finishing touch. Crown moulding is mostly used to decorate the area where the wall meets the ceiling but it can be used in other fashions.
  
  

Kitchen Cabinets

• According to Superiorinteriordesigners.com, you can add crown moulding to the front of your kitchen cabinets, which enhances them and makes them look completely different, which is a lot cheaper, yet equally as effective, than buying all new cabinets. You can paint the moulding a contrasting color from the rest of the cabinet or, conversely, paint the moulding and cabinet all the same color or use slightly different hues to highlight the new feature.
  
  

Around the Door, Framing Technique

• Add a moulding around your doorway or on a wall that is boring and needs sprucing up. Use the framing technique on your wall by creating "frames," using moulding from the floor up to one-third the height of the room and placing the moulding horizontally, continuing around the room to produce architectural interest. The result is a frame.
  
  

Headboard

• Use crown moulding to decorate the wall at the head of your bed. The effect is similar to a headboard.
  
  

Mantle or Bookshelves

• Use crown moulding to create a new mantle for your fireplace. Or use narrow strips of moulding together with narrow boards, attach them to a wall in a spread-out fashion, creating bookshelves or shelves for your knickknacks.
