Lambrequin

1. An ornamental hanging covering the edge of a shelf or the upper part of a window or door.
2. A border pattern giving a draped effect, used on ceramics etc.
   [Think of the filigree ornamental wooden edging on Victorian railway station canopies or on the Colonial Governor’s house.]
3. A heavy protective cloth or scarf worn over a helmet in medieval times.
4. In heraldry another name for mantling.

The word is a surprisingly late import from French with, according to the OED, the first use being in 1725 in Coats Dictionary of Heraldry.
