1920s Sequin Capelet. Silver & White Gelatin Sequins. Shoulder Etsy Original 1920s Flapper Cap Black Glossy Sequins Glass Beads Tulle Art 1980s Fully Sequin Embellished Cap Gold Boardwalk Vintage 20s Handmade Gold Lace Skull Cap w Sequin Flowers at 1stDibs sequin. This is a rare Juliet cap made in the 1920s. What makes it remarkable are two things. First it is made of gelatin sequins which are rarer and harder to find in such extraordinary condition. The gelatin will actually melt if it encounters heat or water. Second most of these are made on netting this gives the sequins a base upon which to apply them. This one (and the other found with it) was made by hand applying sequin after sequin on a cotton cording gold under the gold and black under the black and then forming and stitching the resulting bands of sequins into the cap as you see it. Amazing and a rare piece of fashion history! One size fits all Item# A123
