It looks easier to do it the way shown on that picture than the way I do it. The first time i did mine I didn't do 1 end right and the whole center serving slid up my string over about 5 sessions of shooting. Like a moron,I just kept moving my peep higher and higher and adjusting my sight until one day I noticed it was loose and started measuring things.[&:]

The second timeI used that knot and it's not going anywhere. however, i didn'treverse the loop like shown. i just kept tension on the one end and created a few loops around the string and pulled the tab through wit ha pair of pliers.
