Beaded worked ok, but the mess.... oh god the mess... Also the beaded foam comes with a shiny thin metallic back film which you have to remove before painting. It was dirt cheap, but cost me in time cleaning up / prepping.
Thanks for the compliment all. If you haven't tried making tombstones for some reason I highly encourage it, it uses very simple techniques.
I didn't do anything to hide them so they stuck out some, the camera just doesn't show that. I would throw a white bulb into the mix to pop out some detail as well, having all blue kind of washes it out.
