This is how I make my Wyrdstone tokens, enjoy:
You will need: one scrap of denim (or other tough fabric), one green Taw (large marble), one hammer and as many small coins as you want tokens.
Wrap the Taw/marble in the denim:
Grip Denim in hand and smash Taw/marble (inside denim) with hammer
Remove smashed Taw/marble (henceforth reffered to as 'shards')
Glue individual shIards on to the coins
Paint and flock!
