Balance
Different fabrics, threads and stabilizers can naturally affect the stitch balance
so that the stitch patterns are sewn too close together or not close enough.
This can be remedied with Balance to suit the fabric and produce perfect
results.
Test-sewing
When using decorative stitches, we recommend to test-sew the
stitch pattern on a piece of the project fabric.
If the balance has been adjusted, return it to the normal setting once
sewing is completed!
Normal position
Denser stitch formation - pulling the stitch pattern closer together
(shorter stitch length)
Finer stitch formation - extending the stitch pattern
(longer stitch length)
