PAUL POIRET : 1879 – 1944 (France)
Passementerie literally means “turning by the hand” coming from an early French word.
This term is used for many buttons made from threads of colours as well as silver and gold and/or with braid, beads or fabric. These buttons were made in French Ateliers for Paul Poiret who was a very creative Fashion Designer in the late 19th and early 20th centuries. I find them very intriguing and having been a needleworker can appreciate the workmanship.
Google Paul Poiret and see some of his lovely designs.
