Linha de poliéster Isacord 1000m 6071 Old Lace

This thread runs through my machine like butter—the polyester is noticeably smoother than the rayon I used before. It handled high-speed stitching without fraying once, and the 1000m spool lasted through my whole project.

I’ve been using this thread for heavy stitching on denim and it hasn’t snapped once, which is a relief since other polyester threads give me trouble. The strength really does feel almost double that of rayon, just as described.

Had to buy a spool for a last-minute embroidery job, and this thread ran through the machine like butter—no breakage at all. The strength is really noticeable compared to other polyester threads I've used, and the color is a perfect soft neutral for lace details.
