Attaching bridle/Martingale nameplates
This seems like a stupid question and I think I've seen it here before but I can't seem to find the thread
How do you attach bridle/martingale nameplates, I know where I want them, I just need to figure out how to get them on. They're the Smartpak plates if that makes a difference and they came with what looks like two different sized "pins" (sorry, I don't know anything about hardware so my terminology is completely made up) and then two different sized "caps" that can fit over the pins. Is this doable or should I take it to a tack store? Thanks in advance!
