my current collection is, regrettably, pretty reddit. Mostly stuff bought from a milsurp shop in a city I visit regularly. As far as stuff I actually wear on the regular, I keep the Black Coffee Matters one on my favorite hat. The rest are all scattered around my backpacks. I also have one that says "I Go Gym" on a bulletproof vest I wear when I do sprints (LEO, so it's valid albeit autistic).

I recently bought something from that patch seller list in the OP, but they're still on the way.
