You will notice that the line that if you pulling on the top strand of either loop will adjust its size. When the knot is tied in cotton or other natural cordage friction keeps the loops stable. It is advisable to keep the loads on both loops even. Do not use slippery cordage because the loops might slip out of kilter.
