Superior Thread's So Fine #50 weight 3280yd cones
50 wt./3-ply polyester thread. Designed for quilting, sewing, and to be used in the bobbin. So Fine! #50 is a lint-free, matte-finish, smooth filament polyester thread. Due to its fine nature, So Fine! #50 is an excellent blending thread and loved by both longarm and home machine quilters.
This is my favorite thread! I use it for piecing, sewing, hand sewing, and machine quilting, both domestic and longarm. And I use it in the bobbin when I use other thread on top.
