Hi, Im new here! I'm just getting into leather working and my goal is to start building high quality western show headstalls. I did some research to try and find bridle ferrules, but they don't exist under that google search. So is there a resource to buy ferrules? The closest I came is looking up "tube beads" but they look small? Any shared resources would be much appreciated. Thank you in advance! Janet
