The Dritz 2-Part Eyelets provide a professional finish and a decorative detail to garments, bags, purses and other craft projects. The eyelets are the perfect size for creating laced effects on garments and costumes. The eyelets include a plastic insert that is placed on the post of the eyelet on the wrong side of the fabric . The insert provides extra stability and support, making the eyelets suitable to use with only 1 layer of fabric. The washer is placed over the insert and applied with the hand tools and a hammer. The result is a smooth finished eyelet that is suitable next to your skin or other fabric surfaces. The kit includes the 15 eyelets, inserts and washers, plus the anvil and setter tools for application. Machine washable and dryable.
