This particularly elastic yarn is 0.5 mm thick and is excellent as a companion yarn for knitting and crocheting elastic hats and cuffs. Wound onto a sewing machine spool with 20 meters of yarn each, it is also suitable for direct use on the sewing machine to create gathers or stabilize selected areas of the fabric. The elastic sewing thread is available in various colors and has a particularly high stretchability due to its high elastane content. A groove at the bottom and top of the spool allows the thread to be secured while the work is resting.
