I typically use the first method show here:

However, I'm a bit confused on the second method that is shown. (the Traditional Method)
Step 2 has you tie the back himo in front about chest height. Then proceeds with the front himo. However at no time does it show what to do with the back himo. Something appears to be missing between caption 3 and 5.
