Satin outlines, both open and closed, include a ‘calligraphy’ setting which allows you to specify an angle like an italic pen nib. Generally you will use this setting with Digitize Open Shape but it can also be applied to Digitize Closed Shape with outline stitching selected.
Tip: The same setting can be used with Freehand tools to create more interesting ‘calligraphic’ effects. See Freehand for details.
