Making tiny skulls

These tiny skulls are fairly easy to make and have many uses in my D&D game. I've used them to make a flameskull, convert minis into skeletons, decorate bloodstained altars, and provide some atmosphere in lairs. I start with white polymer clay. It's cheap and available at any craft store and most big box stores. The only tools I use for sculpting these skulls are a flat-head sewing pin, a pinch of poster adhesive putty, and a wine cork. Full instructions with pictures are below the break.
