RE: How to tie in nocksets and a D-loop
Geronimo, I tie the bottom nockset exactly as I did the top one -- with the exception that I make eight wraps instead of four.
If you look at picture # 4, you'll see I'm about to make my fourth wrap before inserting that tag end into the loop created by the dental floss. I'll then pull that tag end back through and UNDER the wraps I just made.
On the bottom nockset, I don't pull that tag end back through until after I've made eight wraps.
