Mettler Poly Sheen Machine Embroidery Thread: This thread has all the advantages of rayon, and much more besides. All tests confirm it. Better elongation and a 50% improvement in tensile strength mean a huge increase in stitch consistency. No breaking threads to interrupt your work. And even under the most demanding conditions, the trilobal polyester thread keeps its brilliance. All that, plus 351 colors and two spool sizes. No one offers more. So it's time to say goodbye to rayon; the future belongs to Mettler Poly Sheen®.
