A serger pulls from four cones at once, which makes buying thread one cone at a time genuinely awkward. These sets fix that. Same spun polyester as our single cones — 40 weight, 2 ply (Tex 27) — with 2,750 yards on every cone.

The four-cone sets give you one color in the quantity a serger actually needs: enough to thread every head and finish a garment without a swap. The larger 40- and 50-cone sets are for people who serge constantly and want the full palette on the shelf. The exact contents of this set are listed in the description above.

Spun polyester combines polyester's strength with the soft touch and sheen of cotton, so it works across every fabric including lightweights, where a heavier thread would pucker the seam. Cones arrive sealed in clear shrink wrap.
