Each stitch is worked in a V-shape, with the needle/thread emerging at the top left arm of the V and then being inserted at the top of the right arm.The needle/thread then emerges at the base of the V and is pulled through the cloth over the working thread. The loop formed is tied down with a small stitch worked just below the point of the V. This tying (‘tacking’) stitch may vary in length to produce different effects.
Also known as the Y stitch or the open loop stitch.
