1. Upper looper thread (blue)
2. Lower looper thread (red)
3. Right-hand needle thread (green)
4. Left-hand 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
Thread tension should be properly adjusted to suit the various types
of work.
The ideal tension setting for most fabrics and threads is between 3
and 5. However this can vary quite considerably when special threads
such as filament, wooly nylon, buttonhole twist (cordonnet), perle
yarn or decorative threads are used.
Infinitely variable adjustments can be made from 1-9. Turn to the left
for less tension. Turn to the right for more tension.
