Mettler Seraflex Elastic Thread is a highly elastic sewing thread designed for stretch fabrics and flexible seams. Made from 100% PTT, Seraflex can stretch up to approximately 65%, helping straight-stitched seams move with garments without needing a zigzag stitch.
For best results, use Seraflex as both the needle and bobbin thread, sew with a straight stitch, and keep thread tension as loose as practical.
