Matelasse (Mat-Las-A'). A term applied to silk or woolen cloth to denote the particular style of its weaving. Such fabrics have a raised pattern on their surface which look as if they had been quilted or wadded. The French word matelasser means to quilt, or to wad. Matelassa silks have usually a rich flowered pattern, and are of one color, the pattern showing only by its slight relief or embossed appearance. The term has also been given to a heavy cloaking fabric, composed of cotton and wool, or silk, cotton and wool mixed; the design being large flower patterns, or brocades of an overshot or embossed appearance.
