Superior Bottom Line bobbin thread
Superior Bottom Line Bobbin Thread
A very fine polyester thread, originally developed by Libby Lehman for Superior Threads as a bobbin fill thread for machine quilting, but it is very versatile and can be used in many other applications. The Bottom Line is a 60 weight/2-ply, lint free, fine filament polyester sewing thread.
As a machine quilting bobbin thread, The Bottom Line sinks into backing fabric without leaving much trace of colour. It balances well with 40-weight and thinner top threads. It is not necessary to match The Bottom Line thread colour exactly to the backing fabric. In fact some of the colours blend into fabrics so well that they appear invisible.
Other uses for The Bottom Line are hand and machine appliqué, detailed quilting, embroidery, stitch-in-the-ditch, trapunto, binding, free standing lace, heirloom sewing. We have not yet tried using it as a serger (overlocking) thread, but Superior Threads does recommend The Bottom Line for this use.
