Rugs are more than something you place at the entrance of your home to keep the dirt out. Rugs can be used throughout your home to both protect your floors and to enhance the style of your home.
Don't Overwhelm the Room
First, try not to overwhelm the room with the rug. A rug should not go from one wall to another in the room that you place it in. A rug is not designed to fill in for carpet.
