Filling stitch is a generic term for surface stitches that are used to fill in specific parts of a design or the grounding around a design. There is no one specific stitch known as a 'filling stitch'. Instead there are many stitches used for filling, including cross stitch, fishbone stitch, satin stitch and tent stitch.
