Fall leaves

If I missed the fall leaf event is there somewhere I can view my leaves that I collected? Will I be able to use them next time there's an event? I was going crazy collecting them and I just realized I had missed the part where you cash them in ):

The event has unfortunately ended for this year, and so has the ability to trade them in, but fear not! When it comes around again next year, your leaves will still be there! I was here last year for the event so I can confirm that my old leaves were still there! I'm hoping next year there'll be a shop to trade in our leaves rather than only cash!

Ok awesome! I was so bummed when I noticed I missed it!
