The big one: Isacord 40wt polyester embroidery thread on a 5000m king cone — five times the thread of a standard spool. Perfect for the colors you reach for constantly (whites, blacks, and your signature shades), and the most economical way to buy the industry-standard embroidery thread. Why Isacord Is the Embroiderer's Favorite Isacord is made from 100% trilobal polyester — a continuous-filament fiber with a special three-sided shape that catches the light and gives every stitch a brilliant, silky sheen. Because the filament is continuous, there are no loose fiber ends: Isacord runs virtually lint-free, keeping your machine cleaner and your stitches crisp. Strength You Can Count On At nearly twice the strength of rayon embroidery thread, Isacord is engineered with just the right amount of elasticity for high-speed stitching without looping, puckering, or constant thread breaks. It sails through dense fill stitches and heavy fabrics like denim — it's even tough enough for automotive upholstery. Colors That Last Isacord is certified colorfast against detergent, chlorine bleach, and light. Wash it, dry it, wear it in the sun — the colors stay true. That's why it's the go-to thread for uniforms, kids' clothes, towels, and anything else that sees the inside of a washing machine on repeat. Endless Possibilities Machine embroidery on garments, towels, hats, and bags Machine quilting and decorative stitching Appliqué and satin-stitch edges with a glossy finish Monogramming and personalization Workwear, uniforms, and other hard-wearing projects The Details 40 wt.
