Not to hijak the thread, but I've never gotten into pin collecting/trading before. My DD is going to be 6 and I am thinking this is something she might be into. Especially with all the great tips for how to display them when we get home. That had never occurred to me!! Do you need to arrive with pins to trade? Do you just buy them when you get there and then trade with others? Sorry, I am a total novice and hoping you can answer some FAQ's for me or re-direct me elsewhere. Thanks!!
