First of all, you have to fetch the original horse hair so that when you are making the keychain, it has the realistic feel. Getting horst hair is not going to be a very difficult task as when you visit a stable, you can easily ask for some strands of hair of horse. And even the caretaker over there need not cut it from the horse's body but every animal shed some strands of hair regularly and you can collect them by yourself.
When you take the strands, what you will have to do is to divide them in three equal numbers of strands. After the division you can create the chain by making braid kind of shape out of it. After making braid, you can attach it to the key ring and can show your creation to the world.
