This fusible bonding yarn is ideal for hemming with invisible seams and can be processed with both the overlock and sewing machine. The yarn goes into the lower gripper on overlock machines. First, the yarn's cutting edge is trimmed in a wide zigzag stitch using the thread. Afterwards, the hem is folded inwards and then firmly ironed from the outside. And, as easy as that, a perfect hem is created with an invisible seam. If a mistake should be made when ironing, the fusible bonding yarn can be loosened again once and ironed on again. The package contains 40 m of yarn and directions for use.
