Wayne,

I have seen several variations for constructing the loops demonstrated by different experienced anglers. Those that I have seen tend to be very similar in most respects.

The link I provided represented the only instructions that I am aware of on the 'net with photos. It is also the method I am most familiar with though I am always looking for a better way. As Capt. Darby noted, splicing loops in hollow cord is not a new technique and you will find instruction for various methods in all manner of publications that deal with knots and rigging.
