2x3 is a great throw rug. The best place for this rug is in a kitchen or exiting/entering a room. You can also scatter three or more of them in a long wood floor hallway to add a different take on a runner. It looks great with tribal or solid colored, no pile rugs.
Placing the correct size rug in your space is as important as choosing the right color or pattern. A rug that it is too small will shift the balance of the room unfavorably. A rug that is too big, especially in open floor plans, may put the area designations off. There are a few rules of thumb, but a picture says it better. Use these handy guides by Interior Designer Lisa Ferguson to make the best choice.
