Correcting Distorted Stretch Patterns
The sewing results of the stretch patterns may vary
depending upon the sewing conditions, such as
sewing speed, type of the fabric, number of layers
etc.
Always test sew on a scrap piece of the fabric that
you wish to use.
If stretch stitch patterns are distorted, correct it with
the feed balancing dial.
