Found myself in the barn one day with no halters around and I didn’t feel like going to the store. So, I grabbed some rope and decided to make one. There are different options, obviously, but what I found to be great about making my own is that you can make a basic halter, get it on your horse or donkey and then custom fit it by adjusting the knots.
The nicest rope halter I’ve found (and best, though certainly not perfect instructions) is this one:

If you can master that halter, make sure you tie the poll straps correctly or else your horse/donkey could get hurt. The halter should be tied with a latch knot like that you see in the picture.
Enjoy.

Notice in the pictures of the halter at that link that the rope they use to make the halter with is pretty thin. I’ve been told that 3/8″ marine/yacht rope is best.
