Two Knotty Boys, Dan and JD, combine a quarter century of rope bondage experience, including tying models for world-renown fetish photographers. Rope bondage blossomed naturally from JD's former work as an industrial rigger and Dan's hobby as a climbing instructor. Meeting in 1999, as both tied applicants for a bondage-modeling contest, Dan and JD noticed their similarity of bondage styles and philosophy and they soon teamed up as the Two Knotty Boys. Ever since, they've been performing live shows, rigging photo shoots and teaching bondage to packed workshops nationwide. Dan's years of performing stand-up comedy and JD's extensive knowledge of human physiology add to their uniquely enjoyable and informative teaching style.
