Isacord 1000m ポリエステル 3335 フラッグブルー 糸

I was a little skeptical about polyester thread for embroidery, but this 1000m spool runs incredibly smooth with zero breaks. The tensile strength is noticeably better than the rayon I used before.

The color is exactly the vivid flag blue I needed for a custom order, and the 1000m spool means I’m not swapping reels mid-project. It’s noticeably smoother through the needle than my old rayon, and I didn’t get a single snag on dense satin stitching.

This thread ran through my machine without a single break, even on dense satin stitches. The tensile strength really shows on high-speed runs, and the flag blue is vibrant without being garish. Glad I switched from rayon for the durability.
