Isacord embroidery thread is 40-weight (40wt), the industry-standard weight for commercial and home embroidery machines. The 40wt designation means the thread is fine enough for detailed embroidery work while remaining strong and durable on high-speed machines. It is made from 100% continuous filament polyester with a modified cross-section fiber for a smooth, even stitch.
