Scarlett W. ★★★★★

Three thousand yards on this cone feels endless when you’re overlocking denim seams, and the black hasn’t faded once through a dozen wash cycles. The 50wt weight glides through my machine without shredding, even at full speed.

Steven E. ★★★★★

This is my go-to thread for all my serger projects now—it glides through the machine smoothly without any shredding or lint buildup. The 3,000-yard cone lasted through several garments, and the black is deep and consistent.

Ellie ★★★★★

This cone is a workhorse—3,000 yards of solid black that glides through my serger without a single snag on denim seams. The 50wt weight is perfect for everyday projects, and it's crisp enough for garment sewing too.
