Soooo one of the ways I partake in my Special Interests is by collecting things in it.

Right now I'm hooked on the Switch, but Switch games are EXPENSIVE and it's just not realistic to collect them. One of my biggest SI are Webkinz, but my family does NOT want me bringing in used plushies from Value Village in the house/having a bunch of Webkinz in my room. My room needs to stay tidy at all times, and Webkinz I guess aren't tidy. Even though Webkinz are like $3 here... But I have too many apparently...

Old games are another big one, but just like the Switch, too expensive. And also my family thinks it's a waste...

So, Reddit, I ask of you, what is something small, relatively cheap, space-saving, something I can really get into, something that won't make my family annoyed that it's around, and something that would scratch that collector's and Special Interest itch?

Should I list my SIs out? Would that help?

Thank you :)
