A sequins of fortunate events. But seriously folks, sequins have long been a mainstay of fashion embellishment. (King Tut had round metal disks stitched to his clothing.) But you can do more than just embellish clothing - they are fun in jewelry too!
A sequin has a center hole. A sequin with an off-center hole is a spangle. A paillette is a metal piece to adorn clothing.
