After reading Monty's & Kelly Marks' books, I'm really keen to try a JoinUp with my horse. The only thing that's holding me back is what if I do it wrong? I don't expect to be perfect the first ( or second or third) time, but I need reassurance that I'm not going to hurt Millie by making a mistake. Would I do any psychological damage, or confuse her? I've practised the angles and positioning on my friends and family, but I need to be sure that I won't hurt Millie before I try it on her! Any help appreciated!
