it was really easy just cut it out of 3mm mdf,
layer it so you get the look of colums or what eva shape you are going for. mine it 3 layers
crave all the bricks on to the mdf
go around the top and cut different bricks out to make it look old, keep cut out bricks to use as fallen bricks on the ground
go around all the coners and archways (were eva you want details) with card in a large brick patteren
cover all the stone with a mix of 1/1/3 grout, glue and water, if you use black colour grout you wont have to under coat the stone
then you paint how eva you like, i air brushed heeps of weathering powder on it
and then flock
