Paillettes
A sequin (fr. paillette "golden grain of sand, gold") is a disk-shaped bead used for decorative purposes. In earlier centuries, they were made from shiny metals. Today, Paillettes are most often made from plastic. They are available in a wide variety of colors and geometrical shapes. Paillettes are commonly used on clothing, jewelry, bags, shoes and many other accessories.
Paillettes are sometimes also referred to as sequins, spangles or diamantes. In costuming, sequins have a center hole, while spangles have the hole located at the top. Paillettes may be stitched flat to the fabric, so they do not move, and are less likely to fall off; or they may be stitched at only one point, so they dangle and move easily, catching more light. Some sequins are made with multiple facets, to increase their reflective ability.
