What a cool site Lynn. Mikie and I played with it last night. Check out the Blakes Hitch. It's the knot that Mike used in Mexico to make an ascender out of the end of the rope. The demo on how to tie the Alpine Butterfly shows a cool technique for tying it one handed. I've been tying the ripala knot wrong for years. (used for tying on fly's to fishing line.) This site will make a great aid for teaching.
