TWO THREAD SERGING
Two thread serging provides a decorative, yet functional seam known as
the flatlock seam. You can flatlock garments ranging from lingerie to fake
fur coats. When sewing with two threads you can achieve a flat, bulk-free
seam. Using it to seam fake-fur fabrics and hand knit fabrics you will find
that the “stitches” disappear into the nap. Enhance the appearance of
flatlock stitch with the use of decorative threads through the looper.
Besides flatlock seaming, two thread serging also provides a sturdy
means of overedging all fabrics.
This can be combined with speciality threads for decorative edges on
ruffles, hemlines, and borders.
Two thread sewing is accomplished through the elimination of two threads
- the upper looper and either needle. NOTE: Use the LEFT needle for a
wide flatlock stitch; use the RIGHT needle for a narrow flatlock stitch.
