Like salt block holders. Seven bucks to hold a brick? Why use that when baling twine comes with your hay for free?
I've also used a ballpoint pen for a hoof pick, and even more baling twine as an emergency halter. Baling twine also keeps my gate shut, and keeps it hooked onto the fence. All in all, its become my best friend.
What cheap or homemade alternatives have you used for horsey tasks?
Also, heres a picture of my salt block and mineral block holders.
