Trial sewing, thread
tension
Sewing test
After threading make a tnal run.
Always use a double layer of fabric
in
order to be able to check the
stitch formation and thread tension
properly.
- Switch the machine on
"I".
- Set all tension dials to
4.
- Raise the front of the presser
foot slightly with your thumb and
position the fabric under the foot
just up to the knife.
- Sew.
- At the end of the seam continue
sewing a
Bcm
(4") long thread
chain.
-
Cut the thread chain and
remove work.
Check your trial run
1 Upper looper thread (blue)
2 Lower looper thread (red)
3 Right needle thread (green)
4 Left
needle thread (yellow)
Perfect
stitch formation is when
both looper threads meet at the
fabric edge. The needle threads
form straight stitches for a
stretchy and durable
seam.
Thread tension adjustments may
be required depending on the type
of fabric and thread being used.
