This particularly elastic thread is 0.5 mm thick and is ideal as knit-in thread for knitting and crocheting elastic caps and cuffs. Each 20 m length of thread is wound onto a sewing machine bobbin and is ready for immediate use on the sewing machine, to produce crimping or to stabilise selected places on the fabric. A groove on the bottom and the cover of the bobbin makes it possible to secure the loose end of the thread, when it is not in use.
