> Pull the cord ends with the hand sewing needle to the back and knot or secure them.
9.6 Sewing a test sample
A test buttonhole should always be sewn on a piece of the original fabric: It is recommended to choose the
same interlining and 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 and for buttonholes which are severely strained. 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.
