Have you ever thought about the impact that flooring has on your overall design scheme? Light colored floors will tend to make your room appear larger.
Deep rich colors used in flooring:from woods to wall to wall carpeting: will reduce your room's apparent size. Unbroken expanses of flooring, such as wall to wall or room size area rugs will enlarge. Smaller area rugs will diminish your room's visual size.
You can even modify the shape of a room visually by changing the shape of an area rug. Last but not least, a beautifully designed area rug can be the focal point of a room or the site of a conversation or dining area!
