Also known as mossoul stitch, plaited stitch, catch stitch or witch stitch. It is so called as it resembles the bones extending from the spine of a herring fish. It is worked along parallel lines and these lines can be marked using an invisible marker.This stitch is a type of back stitch that looks more like a cross stitch than most other back stitches. This stitch is often used in borders and in accents. The herring bone stitch can also be used as a very thick outline and looks especially nice on larger projects.These stitches can be worked closely together to form a dense line or spaced further apart for a looser line.
