Well first off, when a horse turns into you and stands still, it is a sign of respect, although annoying, it's true. The leadline is a good idea to start w/, but I would not use my arms or any part of my body to spook the horse away b/c later on when you wave your arm, the horse will spook even though you don't want it to. Also, when I was first training my first horse I used a crop and would tap on her shoulder until she would shift her weight, then praise. After about one week (15 or so minutes a day) I could use one finger and apply the slightest pressure and she would take 2 steps over. This is a very tedious process, but it is definitely worth it. I did it in the round pen so she would get used to the round pen and when we went in, it was work time. So I definitely suggest just start w/ the tapping of the shoulder, and then after your horse has that down, when it is facing you, you can use the crop, leadline, etc. and make it circle you. Hope it works, and let me know how it goes!
