Who does not appreciate the beauty and warmth of a rug for an otherwise bare floor? Rugs are made of many materials and come in many sizes and shapes. Rugs have many purposes besides just decorating the floor.
Who says size doesn't matter? Who would want to choose a rug that is so undersized or too big? Standard sized rugs, such as 3 x 5's and 4 x 6's, are usually placed in rooms to accentuate furniture and inglenooks. These rugs, and even smaller, can also be used in entry ways, kitchens and bathrooms as a floor mat. Larger rugs, like 6 x 9's and 9 x 12's, are commonly used for living rooms and dining rooms. Again, know where you want the rug to be placed.

You can get area carpets for children with games and bright children's designs on them. You can get bath mats that are washable.
