Guipure: A type of openwork lace made with fine wires wrapped in threads of cotton or silk. The decorative motifs are connected with links called brides, a word that in this sense is related to bridle. (However, guipure lace is traditionally worn by brides of the other kind.) From French guiper, to cover with cotton or silk. Pronounced GHEE-pyoor.
