Seven strands of black, Dacron B-50 and seven strands of red, Dacron B-50.
Cross the two bundles about ten inches from one end.
While holding the end where the bundles cross firmly, I start twisting one bundle (Red) away from me and over the other bundle towards me. Then twist the Other (Black) away from me and over the red one towards me over the black bundle.
When I have the twisted part long enough to make a loop, I am ready to tie it all in to make a permenent loop.
Create a loop and wrap the red bundle with red and the black bundle with black.
I use the same twisting procedure I used above, I continue one down the string bundles.
Until I have gone past the ends of the shrter bundles, and the loop is all tied in. I trim off the stray ends later to make it look neat.
