Customer offered to promote app at conference

During my second customer interview for Fantasy Congress, we discussed a big upcoming conference that the customer was attending (national social studies educator conference). She will be hosting a discussion at the conference and brought up the idea of passing out Fantasy Congress freebies or materials to the attendees. Unclear if Fantasy Congress will be part of her discussion, but she is very supportive of the project and using it in her classes this semester.

I'm going to send her a bunch of stickers. Stickers are great right? They don't have the full website url (they just say "Fantasy Congress"), so I'd like to attach them to some little cards that have the url and social handles. Time to get a crafty.
