I'm a rank beginner. I am confused about leaders and tippets. As I understand, the backing is connected to the line on the reel. Do I attach a leader, tippet or whatever to the end of the line? The terminology and the demonstrations in my fly fishing videos don't address where and how to attach a leader and/or a tippet. Leader on the end of the line, then tippet? I know I'm just missing it, but I need Help!
