I have a "collection" of just straightforward souvenir pins from various parks, resorts, events, museums, etc. I've been to, but my REAL collection began quite organically. I collect pins related to Jules Verne and 20,000 Leagues Under the Sea, which have Disney characters on them. It started as souvenirs from Tokyo DisneySea, when I picked up pins for their 20,000 Leagues Under the Sea and Journey to the Center of the Earth rides that had Mickey and Minnie on them. Then when I started actually collecting pins, it grew from there. Every time since then, when I've considered starting another collection from scratch, it never really goes anywhere. I thought about a Main St. USA collection, but nope. Then a Fantasia collection, but that didn't happen either. I think I just don't have the will or money to start a collection for the sake of having a collection. I'm still pretty content with the collection that started naturally, even if I pretty much have everything I want for it now.
