Passement (Pas'-Ment). A decorative edging or trimming, especially a gimp or braid, wrought in complex and fanciful patterns. This sort of embroidery was first made as a trimming for garments in the 17th century. In those ancient days it was an expensive material wrought with small beads and discs ot gold, and worked with colored silk thread, laid in small round rolls alternately beside the gold, so as to lend a tinge of green, crimson, pink or blue to the tissue.
