If a buttonhole is to be sewn at right angles to
a seam, we recommend the use of the height
compensation plates for buttonholes (available
as optional accessory).
Using the compensation plate is recommen-
ded when sewing buttonholes in difficult
fabrics. It can be used with the Automatic
buttonhole foot no. 3A or the buttonhole foot
3B.
