So Fine! #50 is a lint-free, extra smooth #50/3 filament polyester.
Here at Quilts on the Corner we love this in our bobbin while using Magnifico on the top. It is "so fine" that we can more yards on a bobbin.
I use #402 for all my light quilt piecing. Won't use any other brand. So Fine by Superior is the best.
