Pin trading is really alot of fun once you start. A lanyard is worn around the neck to display your pins. We usually stop at the Disney outlet @Premier Outlet Mall and buy a few discontinued ones for trading. Then you can approach any CM and check out their pins and trade for one you want. Other park guests may ask if you'd like to make a trade, too. You don't have to if you don't want, but a CM must trade if you ask. I've collected a lanyard full of Tinkerbell pins that I will never trade but love to wear because they make me happy. I've bought some that appealed to me on E-Bay that are no longer available. Every person I've introduced to pin trading/collecting has become hooked in a matter of minutes. I hope you enjoy it if you decide to give it a try.
