YLI Silk Ribbon is the industry leader for a good reason. All our silk ribbon is 100% pure filament silk which means it is the highest quality you can buy. Synthetic or spun silk products simply don't measure up. There's no substitute for quality. The uses of 100% pure silk ribbon are innumerable but include hand and machine embroidery, doll dressing, decorative serging, smocking, weaving, etc.
