@rLok I'm also gonna add that if you do decide to try making a few freebies, I've always had amazing reactions to just handing stuff out to the people immediately close to me.
I've done random stickers from sketchy packets I've bought from Etsy or a kpop store; keychains or bracelets (even 5-10 is more than enough!); buttons... Extra photocards to hand out, including homemade ones, are always so loved! So even if you guys only come up with a tiny handful of things, it would be a huge hit - esp from a 9-year-old ;)
