9.6 Sewing a test sample

Always sew a test sample of the buttonhole on the same fabric: It is recommended to use the same stabilizer
and to select the same buttonhole. The test sample should also be sewn in the respective direction. By
sewing a test sample the settings can be adjusted until the sewing result is satisfying.
When working with soft loosely woven materials or for buttonholes which are highly stressed, it is worth
underlaying the buttonholes with the Straight stitch buttonhole No. 59. This is also recommended to
reinforce buttonholes in leather, vinyl or felt.
Alterations of the balance when sewing a manual standard buttonhole as well as the keyhole and the round
buttonhole affect both beads in the same way. With the manual keyhole or round buttonhole, the
alterations affect both sides in the opposite way.
If the stitch counter function is used and alterations are made concerning the balance, the alterations affect
both buttonhole beads differently.
