So Fine! #50 bobbins
50 wt. 3-ply L-style and M-style prewound polyester bobbins. Designed for embroidery, quilting, and sewing.
So Fine! Prewounds are lint-free, matte-finish and smooth. Due to its fine nature, So Fine! is an excellent blending thread and loved by both longarm and home machine quilters.
