Sequins are commonly used on clothing, jewelry, bags, shoes and lots of other accessories. Large sequins, fastened only at the top, have been used on billboards and other signage, particularly prior to the development of lighted and neon signs. Signs made with sequins were called schmaltz, as were the sequins themselves in that context.
