Isacord is a high sheen trilobal polyester embroidery thread which combines maximum washability, durability and top colorfastness. At nearly twice the strength of rayon thread, Isacord is the smoothest running and most reliable polyester thread produced. It provides just the right amount of resilience for high speed sewing, while eliminating looping, puckering and thread breakage. It can be used for both sewing machines and sergers - great for art quilting, surface design, garment sewing and embellishment. A unique 'snap down' base prevents thread loss and provides for easy storage. Recommended especially for Bernina embroidery machines. Isacord Embroidery Thread, 100% Polyester, 40 weight/2ply, mini-king spool, 1094 yards/1000 meters, Made in Germany. Color: #2520 Garden Rose.
