After seeing so many people use foam core to organize board games, I set about doing the same for my Pathfinder Pawns.
I posted photos and a little more details on Reddit
In total, one bin and one original PF box holds all the pawns from the following sets:
2x PF Pawns Beastiary 1
1x PF Pawns Beastiary 2
1x PF Pawns Skulls and Shackles
1x PF Pawns Rise of the Runelords
Note that I store all minis upside down so their name is visible.
