So Fine! Thread #431 Navy - Spool

Finally, a polyester thread that doesn't fray or leave lint all over my machine. The 550-yard spool has been perfect for my serger, and the smooth finish glides through layers without breaking.

I was skeptical about polyester thread for my serger, but this 50-weight 3-ply runs through without a single lint ball. The 550-yard spool is lasting me through several projects, and the navy color is rich and consistent.

I was a bit worried the 50 weight would be too thin for my serger, but it runs through smoothly without any shredding. The 550 yards per spool is generous for the price, and the navy color is a true, deep shade.
