Mettler Seraflex 130m light yellow elastic sewing thread is the ideal innovation for sewing highly stretchy fabrics with a simple straight stitch. Developed with flexible PTT (polytrimethylene terephthalate), this innovative thread provides up to 65% stretch in the seam, following the natural stretch of knits and jersey without breaking the stitches. The 130-meter spool in light yellow has a luminous and soft touch, and is recommended for visible or invisible seams in sun-resistant and spring-like materials. Its use with reduced thread tension on a domestic sewing machine effectively replaces the overlock stitch in hems and necklines. It is perfect for making children's sportswear, swimwear, leggings and t-shirts in stretch knits.
