Use Single Stitch 
to add one stitch at a time each time the pen is touched to the tablet (or with each left-click of the mouse). Alternatively, drag the pen across the tablet to pull out a line, then the single stitch point will be added at the point where the pen is lifted from the tablet.
Add as many single stitches as desired. Right-click to deselect the function, or simply select another tool.
