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.
It is worth underlaying the buttonholes with the Straight stitch buttonhole No. 59 when working with soft
loosely woven materials or for buttonholes which are highly stressed. This is also recommended to reinforce
buttonholes in leather, vinyl or felt.
Alterations to the Balance when sewing a manual standard buttonhole as well as the keyhole and the round
buttonhole with length measurement affect both beads in the same way. With the manual keyhole or round
buttonhole the alterations affect both sides differently.
If the stitch counter function is used and alterations are made concerning the Balance, the alterations affect
both buttonhole beads differently.
