ON Edit: Looked at the link above, and it is the same as I described, except that I pull until both ends wind up inside the wrap ....and the link has pictures!
Here's how I wrap anything in cord, from fishing pole guides to spear handles:
Make a u shaped loop in the cord slightly longer than the area to be wrapped.
Lay the loop over the area to be wrapped, open end to the right (right handed person), with the closed end an inch or so past where the wrap will end.
Start wrapping from the open end, wrapping over the short end of the loop. Pull each wrap tight.
When you reach the end of the wrap, pass the free end of the cord through the loop, and hold tight with the left hand.
With the right hand, pull on the free end of the loop. This will cause the loop at the end of the wrap to close up, and then start pulling the other end of the cord inside the wrap.
When the loop is pulled inside the wrap about 1/4 of the way, trim the end of the cord, then pull until the cut end is inside the wrap. Then trim the loose end you were pulling on, and tuck the end up inside the wrap.
Done right, the two ends of the wrap cord end up under the wrap, interlocked together in the middle.
If the wrap was done tightly, it will pull rather hard, but it won't work loose.
