A Celtic button knot is a stopper knot on a single rope that results in a spherical decorative knot with hair braid / basket weave pattern. It is essentially a single strand Turk's Head Knot that is structured such a way that it is effectively tied around the rope itself, creating a stopper. It typically is used as a button, or as a knot securing the end of the rope from fraying.
