BOTTOM LINE
What is Bottom Line thread used for?
Bottom Line is a 60 wt./2-ply polyester thread that has been designed to be used as a bobbin thread. It's fine diameter helps it to blend well and its filament construction makes it extremely smooth, so it glides through fabric when stitched. As a lint-free thread, you will find that the blending tones seem to disappear into colored fabrics, creating a nearly-invisible presence.
