Rugs are an important decorating tool. They add interest and warmth but above all, they help define different areas by anchoring the space. In an open plan arrangement, rugs are necessary to help clarify different spaces such as dining and seating areas. If you use rugs in the same open area, it's better to have them matching or complementing one another in style and colours for harmony. The size of the rug you use is also very important. You don't want them wall to wall, but rather a suitable size for your furniture and dining table. If they are too small they just look wrong and unbalanced.
