From verso of card: "Take an ordinary handkerchief, hold Corner No. 3 in the left hand, and with the right hand grasp Corner No. 2 (between thumb and first finger) and Corner No. 3 (between first and second fingers). Twirl the handkerchief vigorously outwards so that it coils itself into the rough shape of a rope. Still twirling, pull outwards by Corners 3 and 2 and the handkerchief will continue to grow longer."
