The Stipple settings panel in the Object Properties docker helps you control the stippling effect.
Adjust Loop spacing for tighter or more open stitching.
Adjust Chord gap for smoother or sharper curves.
Adjust Inset step to set the margin from the object border.
Control run stitch settings via the Stitch settings panel. Adjust Stitch length for smoother or sharper curves. The Run count defines stitch repetitions – e.g. 1, 3, 5, 7, 9 – and hence stitch bulk.
Stemstitch and Backstitch offer further settings.
