I made this for a Good Morning, Texas segment a few months back, but I'm keeping it for my craft room (coming, summer 2016!).
I bought a bunch of these spare parts brads from Hobby Lobby when they were half off (which is about every other week). It took 2 packages. I just glued them down to the metal part of the clipboard. You can use a glue gun, but I'm going with gorilla glue so it will stay on a little better.
I'm going to use this to trade out inspirational sayings, to do list etc.
