Hello, This is one of those things I'm not real good at explaining here, but I can tell you where I learned it. I watched Wally Marshalls first DVD, Crappie Fishing Secrets. During the part where he is tight line trolling in deep water he shows and explains how to do this. The loop knot he uses is very easy to tie and I've straightened out a lot of hooks with it getting unhung.
Hope this helps! :D:D:D:D
