Repetition is a design principle where shapes, lines, forms or colors are repeated in a pleasing manner.  Repetition is important because it will bring a sense and order to your room and home.  It will make everything cohesive.  In this room (an Ivory Homes model and 2011 Salt Lake Parade of Homes entry) you may notice that the same colors are repeated throughout the room.  The yellow chairs have teal pillows, the teal chair has a yellow pillow and the cream-colored couch has both. The colors are also repeated in the accessories.   Your eye travels around the room without skipping.  A good rule-of-thumb is to repeat an element, like color or shape, at least three times in a room or throughout your home.
