Lambrequin (Lam'-Bre-Quin). A term which has passed through several stages of evolution to reach the particular place it at present fills among dry goods. In mediaeval times, lambrequin signified a piece of cloth worn by a knight over his helmet, for protection from heat and dust. Next it is found in architecture and painting, the lower edge of the lambrequins in such decorations being represented as jagged or scalloped, but consisting of the graceful outlines suggestive of the lambrequin floating from a knight's helmet. At present the word indicates a piece of textile fabric, or leather, hanging by one of its edges, and having the opposite edge slit-ted, scalloped, or otherwise cut in an ornamental manner. In upholstery, a sort of curtain covering the upper part of an opening, as a door or window, and often forming a fancy cornice to the curtain proper.
