OK say you have a ring, you know the common thing to do would be to just pass that through, flip it over and you have a classic “Cow Hitch”.
MUSIC PLAYS The only problem with a Lark’s Head is it might not hold on you. In the long term it might work its way free.
So to prevent it from working its way free you can always add a half-hitch here on the ring and that’s not going to work its way free at all. OK so, a Lark’s Head with a half hitch lock. Or you can go in this direction and put your half hitch lock here. Cow Hitch with a half hitch lock. Again, that’s not going to work its way free.
