Entrances. Most people think area rugs are too large for an entrance but they are available in the smaller sizes. So whether you have a grand entrance or a smaller entrance you should consider making a decor statement where people enter. You could place a beautiful oval braided rug at your entrance or a bold rectangular rug. Make it blend or stand out. Your choice. An area rug at your entrance also has some function use as well. The worst thing for your carpets is oil dirt and sand. Even a clean pair of shoes will track particles onto the carpet. Using an area rug will help reduce what gets tracked because it will act as a catcher. If you have a tiled or linoleum entrance it will also keep it looking cleaner as the rug can pick up the dirt or mud off of shoes and it's easily cleaner up with a vacuum.
An area rug is often the defining feature of a room and with this in mind should be selected with care. The rug you choose will set the tone for the overall feel of the space and will be the factor that ties in all of the different components of the décor. If you have a large space that is divided into more than one area of use rugs can bring these spaces together as a harmonious whole or can be used to further define the different regions of the room to give the feel of separate living areas.
There are other kinds of small carpets like rag braided sisal chenille and shag made of various kinds of materials like cotton silk leather wool and synthetic fibers. You can get area carpets for children with games and bright children's designs on them. You can get bath mats that are washable.
