Serger Thread – Types and Benefits of Using Sergers
Serger thread is finer than regular sewing machine thread, in
order to avoid bulky seams. It must be smooth and consistent
in diameter since it passes through so many guides in a
serger. Serger thread should not leave a lot of lint, so that
it does not clog the serger. Serger thread is sold on a large
spool, called a cone, and generally has a length of 3000
yards. Serger thread can be made of cotton, polyester, nylon,
or wooly nylon. When choosing thread, select colors that
blend with your fabric.

Benefits of Sergers and Serger Thread
Sergers use multiple strands of thread to form a zigzag pattern
across the edge of your fabric to keep it from fraying. This makes
it ideal when working with lighter weight fabrics such as knits and
formal materials. Sergers also form a cleaner and more professional
edge quickly. You will notice that a serged edge looks very similar
to the edges you will find on storebought clothing.
Serger thread is needed when using a serger because it is made
for the interlocking motions of the serger. It will glide quickly
and easily through the machine as well as prevent thick knots from
forming along the edges. Serger thread is also specially wound so
that it will not tangle on itself, also preventing knots from
forming.
