This particularly elastic thread is 0.5mm thick. Each 20M length of thread is wound onto a sewing machine spool and is ready for immediate use on the sewing machine, to produce crimping or to stabilise selected places on the fabric. The elastic thread's high proportion of elastane makes it particularly highly elastic. A groove on the bottom and the cover of the spool makes it possible to secure the loose end of the thread, when it is not in use.
