So Fine #50 is a lint-free, low/medium sheen, smooth #50/3 filament polyester. Due to its fine nature, So Fine #50 is an excellent blending thread commonly used for top stitching 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.
