Isacord 1000m Polyester 3900 Cerulean Thread

The color is a perfect deep cerulean, and this polyester thread is noticeably stronger than the rayon I used before. It’s smooth through the needle and has held up great on a heavy denim project.

This thread runs through my machine like butter—zero fraying or breakage even at high speeds. The color is a true, vibrant cerulean that pops beautifully on dark denim.

I’ve been using this cerulean shade for a few weeks now, and it runs through my machine so smoothly that I barely have to adjust tension. the color is rich and even, and the 1000m spool lasts a good while on big logo jobs.
