Rugs are a type of floor covering that come in a variety of shapes, sizes, and materials. TOUPEES, which have seven letters, are a type of wig or hairpiece worn to cover baldness or thinning hair. MATS, which have four letters, are a type of rug that is usually placed at the entrance of a building or home to provide a barrier from dirt and moisture. Both TOUPEES and MATS are types of rugs, but they serve different purposes.
