The subject of rug and carpet weaving is vast. As with other carpet construction, serviceability depends on density, fiber content and intended use. When using a rug on top of carpet, carefully consider surface textures. Textures can be identical when combining a solid color and a pattern. Two solid colors, one on top of the other, require different textures for the most effective result.
Research shows that soiling appears most readily on white or light yellow floor coverings.
Dark colors show lint and accumulated dust, while medium colors, color blends and patterns are best for hiding soiling. If a rug is being used primarily to reduce soiling on another floor surface, be sure the rug selected will tolerate the cleanings required. A rug pattern may be simple or very complex. Several patterned rugs can be used in a space very effectively. Be careful, though, to plan this type of arrangement so each rug maintains its identity and beauty, and the space does not look cluttered.
