G`day Folks, During the past week I`ve made a couple of polystyrene stone walls for my layout https://platform1mrc.com/p1mrc/index.php?threads/great-chesterford-junction-part-two.6/page-24 and they were very easily done and coloured up with artists acrylic paints. PVA is good enough to glue them into place or you can use whatever takes your fancy. Creating the texture and stone courses is dealt with in the video below. These walls are more a simulation of stone rather than an accurate copy, however when placed into your scenery, I think they give a reasonable representation of a stone wall.
