Flagstone bases

[Trix]

Hi all, Trix again
I settled on doing an army based upon the City of Gold but I don't know how to do the Flagstones for some of the bases for the army :/.
Any ideas ?

Cut up bits of cerial box in flagstone shapes,
glue to base, paint aproperately, posibly glue some flock where aproapite.

Otherwise,

Thin layer of Sculpey on a metal/glass sheet that's ovenproof. Before you bake it, use a pin or something to score the lines in it.

Once it's baked, scrape it gently with a small spoon or a file or something to create a weathered finish.

Then glue to the miniature's base, paint and flock as appropriate
