40 wt. 2-ply high-tenacity trilobal polyester thread. Designed for quilting, decorative stitching, and embroidery. Magnifico is a bold, strong thread created for quilting and embroidery. Magnifico is an extra-strength, high-sheen polyester that can handle the speed and tension of longarm and commercial machines, while displaying bold and beautiful shades of color. Unlike most high-strength trilobal polyester threads, Magnifico is 'heat set' in processing, which eliminates unwanted shrinkage.
