Did you know that knife pleats have a 3:1 ratio, which means that three inches of fabric will create one inch of finished pleat? Our Italian Black Knife Pleated Trimming measures in at one inch and features a black, slightly reflective design with incredibly detailed craftsmanship. Use this classic trimming to add detail to a waistline or to create accessories such as bracelets. You can even use it to add a sophisticated touch to curtains and upholstery!
