Holding the rope with the left hand, with the right lead strand a in the direction indicated by the dotted line, viz., under strand b and up between strands b and c (Fig. 61).
Then with strand b form a similar loop, enclosing strands a and c, and bringing the end of strand b up between a and d (Fig. 62).
Now with strand c form a similar loop, enclosing strands b and a by leading the end of strand c up through the loop e in strand a (Fig. 63).
