Use Single and Triple Run tools to digitize lines of simple run stitching. Digitize simple runs as you would any other outline stitch. Adjust settings via Object Properties.
For both run and triple-run stitches, stitch length can be adjusted via Object Properties to suit the shape. If a line has tight, sharp curves, reduce stitch length, for instance, to 1.8 mm, so that stitches follow the line more closely. To reduce the stitch count for flatter curves, increase stitch length.
Choose between run or triple run for thicker lines...
