@all - well, since the unanimous consensus is black, then black it shall be. (ok, vossy said grey, but since there is no grey, im gonna assume he meant black. Whatever youre smoking, vossy, its affecting your eyesight...

)
@prim re: "can I ask why you broke off the edges and stuck them to GW bases? "
I didnt. The whole thing theyre standing on is made of resin, including the "GW base" bit. I made a whole bunch of eldary tiles (like, 6" square of em) and then broke it into bits and stuck em roughly onto GW bases. I textured the bits in between tiles with sand, for a sand-blown-over-ancient-civilisation feel, then cast the whole shebang in resin. The ones on these minis are the most tiley and least sandy ones, but theres plenty of desert to go around overall.
thanks for the input, chaps - im off to paint 60 small bases black round the edges...
