Isacord 1000m Polyester 4074 Dimgray Thread

This 1000m spool of 4074 dimgray polyester thread is running through my machine like butter. The strength difference from my usual rayon is noticeable, and it hasn't frayed once.

This thread runs so smoothly through my machine that I barely have to adjust tension between color changes, and the 1000m spool lasts through multiple large designs. The matte dimgray shade looks perfect for subtle outlines and shading work.

My industrial machine usually snags on cheap threads, but this 100% polyester ran smooth as silk through even the tightest lettering. The tensile strength is noticeably better than the rayon I used before—no breaks during a dense 10,000 stitch design.
