Hemming with the twin needle

Use the twin needle to make beatiful topstitch
seams.
Using the twin needle you can add a
professional touch to hems on stretch materials
such as T-shirts, knitted articles or cycling
shorts both quickly and easily.
Twin needles are available in different widths.
The traditional width for topstitching is 4 mm.
To prevent the needle from striking the needle
plate, you must make sure that you select the
center needle position
• First fold and iron the width of fabric desired
for the hem.
• Then topstitch the hem from the right side.
• Finally, cut the protruding hem edge back to
the seam.
Use only a stretch needle when sewing stretch
material!
Tip: On diffi cult materials such as ribbed knit-
wear it is advisable to baste the hem before
topstitching it.
On page 11 you will fi nd a description of how to
thread the twin needle.

Smocking effect with elastic threads
Fine, light fabrics such as Batist, rayon and silk
are particularly suitable for beautiful smocking
work. For smocking work with the elastic
thread, you should use an additional bobbin
case and wind the bobbin by hand with the
elastic thread. As the elastic thread is much
stronger than the normal bobbin thread, the
tension of the bobbin case must be set at very
low.
Don't forget, the higher the bobbin thread
tension, the more intense the gathering effect.
• Sew a test seam to determine the level of
gather.
• Mark the fi rst line on the right side of the
fabric and sew along it.
• Each additional seam can be sewn at a
presser foot's width from the fi rst row.
• When sewing several seams next to one
another, you must stretch the fabric to its
original length when sewing the subsequent
seams. Otherwise, the gather will be
irregular.
• Knot the threads at the beginning and end
of the seam on the reverse side.
