I made these pain tokens to record the number of enemy units slaughtered by my own units so I can keep track of the benefits bestowed on my blood soaked units.
Using a small flying base, I pushed a mound of milliput putty onto it and then using an entire (20 models) zombie regiment I pushed the parts into the putty leaving space on the top to push a wet dice into. The dice is wet so the putty doesn't stick and I can retrieve it.
I sprayed them black and then dry brushed with a few shades of red. I then mixed black with red wash and gloss varnish and painted it all over the pieces. Finally I gloss varnished the pieces to mix them glossy (well duh) and to make them hard wearing as gaming pieces.
