I did t differently...I cut one of the feet out and then cut small holes in the top near where I cut and ran a showlace through it and around the noseband.
Good luck and I hope it works for you. It did not work on my pony but it works for my friend's TB. D you have your horse on any supplements? I use Magnesium on my pony and it helps her a lot. Yo can also use Melatonin.
