Mettler Seraflex 130m blue elastic sewing thread provides exceptional stretch for seamless joining of stretch fabrics without the need for complex stitches. Made from high-precision elastic PTT polymer, this innovative thread follows the elasticity of fabrics up to 65%, ensuring flexible seams that won't tear under tension. The 130-meter spool in classic navy blue blends harmoniously with stretch denim, sportswear, and uniforms. Direct application with a straight stitch and gentle tension eliminates the need for bobbin thread or zigzag stitching. It's the right choice for making stretch trousers, tracksuits, knitwear, and casual wear.
