So Fine! #50 is a lint-free, low/medium sheen, smooth #50/3 filament polyester thread. Due to its fine nature, So Fine! #50 is an excellent blending thread commonly used for topstitching applications when the fabric or backing design is to be more prominent than the quilting.
So Fine! #50 also makes a wonderful bobbin thread and is available on prewound bobbins for convenience. Reduce the time spent cleaning your machine by using a quality thread like So Fine! #50. Even twist means smoother sewing and less breaks.
