Conservatory Stone Walls

Not a lot to show for progress but what the pictures don't show is that I sanded all the pieces and repainted them. I've started to apply the "stones" to the walls. It is like putting a jigsaw puzzle together without having the help of seeing what the final picture should look like.
I have two sections of the walls glued with the "stones". I'll need to apply the Polyacrylic to seal them as the "stones" are made from high density casting plaster. I have to let that dry overnight and then I can put in the mortar. What you see in the pictures as brown will be filled in with gray mortar. I only painted a bit of the background to make sure I had a good coverage on the rails but no need to waste time or paint on an area that will be covered anyway. Getting all the walls to this stage will take a lot of time so this will probably be the last post for at least a week...maybe two.
