How to tie a perfect boltsnap from Rich Walkers wesbite Wreck and Cave.
The site is great, but I miss a photo. Let me explain: on the last photo, the ends of the line seem to be molten but not welded to the loops (excuse my horrible English, I will try again :-P
The idea is to get a redundant tie off. It is not the same line with three loops and one only final knot; the idea (at least as was taught to me) is to get three independent tie offs.

...First photo flattens
on the middle and second one flattens
on the ends. For me, it is preferrably the second system, because it welds on the three loops, getting three independent loops:
