I print my own miniatures for use with Pathfinder. I buy the PDF version of the Pathfinder pawns and print out the pages that I need to use, cutting and gluing the pieces as necessary. However, I was having trouble finding decent bases for them. The bases that are for sale on the Internet either didn't fit or were too expensive.

So, I decided to use 3/4" mini binder clips (Amazon).

I simply attach the binder clip to the paper miniature...

...and then remove the arms. I'm left with a sturdy stand that can be stood upright on the battle mat.
