I've been afraid to use Sulky specialty threads on my longarm machine. What are the basics for doing this?

While all Sulky threads can be used on LA machines, some may need special handling. Some of the most important things are: Sew more slowly; use a soft, smooth thread in the bobbin; and use a needle with a larger eye, even when the thread seems very thin like the Sulky Original Metallics, Sulky Sliver Metallics, and Sulky Holoshimmer Metallics. It is not unusual to need to adjust the top tension on LA Quilting Machines when using decorative specialty threads.
