So Fine! #50 is a #50/3 lint-free and extra smooth all purpose polyester thread. Each Cone has 3,280 yards. Excellent for Sewing, Serger, Bobbin Thread, and Quilting.

PS- You're allowed to use this on boy quilts, in fact, did you know pink used to be a 'masculine' color? ((Which is dumb- colors are colors and people can like whichever one they want.))
