Stretching "0.6"
The front feed dog (0.6) covers a shorter distance than the rear feed dog (1). The material is stretched under
the presser foot which helps to reduce puckering. This setting can also be used to deliberately stretch the
material.
1 0.6
> To prevent seam puckering, reduce the differential feed to a value between 0.6 and 1.
