Fusible Bonding Yarn, 40m in Length and Washable up to 40 Degrees PRYM # 987170

This fusible bonding yarn is perfect for creating invisible hems and works seamlessly with both overlock and sewing machines. For overlock machines, it's inserted into the lower looper. Begin by trimming the yarn's edge with a wide zigzag stitch, then fold the hem inward and press firmly from the outside. This simple process results in a flawless hem with an invisible seam. Should any errors occur during ironing, the yarn can be easily detached and re-applied. Each package includes 40 m of yarn along with usage instructions.
