Sulky 40 weight thead is a light weight but exceptionally strong, silky rayon thread. It is colorfast and both washable and dry cleanable.
It is the preferred thread for "free-motion" machine embroidery as well as computerized embroidery. Most computer embroidery designs are digitized for Sulky 40 weight rayon thread.
A size 12/80 machine needle is most commonly used with Sulky 40 weight rayon unless the thickness of the fabric/stabilizer calls for a 14/90. It can also be used in the bobbin when working on projects where having the same color bobbin thread as top thread is important.
