58 Needle, thread, fabric feed
Feed-dog and fabric feed
Feed-dog and stitch length
With each stitch the feed-dog moves forward by one step.
The length of this step is determined by the stitch length selected.
With an extremely short stitch length, the steps are also short.
The fabric moves under the foot quite slowly, even at full sewing
speed. Buttonholes, satin stitch and decorative stitches are all
sewn with a very short stitch length.
Important
Let the fabric feed evenly! Pulling or pushing will result in
gaps.
