With the right tension settings you get a regular stitch with your top thread, then the five tiny stitches that bring the invisible bottom thread to the top, regular stitch, five tiny invisible stitches, etc.

The result looks as if you have spaces between your regular stitching but in reality there are five tiny stitches in between each regular stitch that you can't see. The effect gives it the appearance of hand quilting.
