Started collecting coasters with my roommate back in Boston 5 or 6 years ago and have ones from all over like Portland, Montreal, Barcelona and Japan. My favorite custom coasters from different places like local spots around nyc or wherever.
I added postcards a couple years, some are related to travel but a lot of them are from different art museums I go to. I usually go to the museum store after I’m done and pick out a couple paintings or pictures of installations I really liked.
I put a lot of them on this cork board in my apartment and I like it a lot because most have a good story behind them.
