Technical section, general
If you set the differential feed to 2.0 the
front feed dog moves at twice the speed
of the rear feed dog. This means that the
front feed dog moves twice as much fabric
as the rear feed dog. This gathers the
fabric.
In this way, you can prevent the seam
from stretching when you work with knits
such as jersey or cable knits. The seam will
remain flat (A).
However, you can also use it to achieve
fashionable effects such as the gathered
effect with very fine fabrics (B).
The following table includes notes on setting the differential feed. Always test your
setting first on a piece of scrap fabric.
