These were quick and fun to make.
If you have spare miniatures you do not know what to do with, you can quick paint them into stone statues (aka medusa victims).
But another quick way to get use out of such minis, is to make them into ghosts.
Simply spray them white and give them a wash of Games Workshop’s “Nihilakh Oxide” from their technical range. You can add a few red eyes, but it is not a must have.
This is so quick, that basing the minis take longer than the paint job!
