Isacord 1000m Polyester 4010 Caribisch Blauw Garen

I've been using this for a tricky satin stitch project, and the 1000m spool is lasting way longer than expected. The polyester thread so far hasn't frayed or snapped once, which is a huge improvement over my old rayon.

This thread runs through my machine without a single break, and the Caribbean blue is even prettier in person than on screen. I’ve tried other polyester threads before, but the strength here is noticeable—my last project held up perfectly after multiple washes.

The color is so vivid it makes my digitized designs pop, and the thread runs through the machine without a single break during a three-hour project. It's noticeably smoother than the rayon I used to buy, and that strength claim really holds up under tension.
