I have been looking for "Garden of Morr" type scenery for a while now off and on suitable for Warmaster. There's much more choice in terms of churchs and ruins in 15mm, thanks to WW2 systems like Flames of War.
However, when I looked around for N-Gauge railway stuff, I found some greater options opening to me. I've bought a couple of white metal packets, but it's £4 for only a handful of very thin, very small headstones.
Then I found that a company called "Dornaplas" makes them in a little plastic sprue!
I put a Dark Rider strip next to one so you can see the scale of them.
I'm planning on using them on Vampire command stands and in little strips of vignette pieces to make up a graveyard next to my ruined church.
