Stonework continued

I cut out a double door section in the "kitchen area" for a future idea.  I cut a little area out of the back room so I could see & paint better.  Then, I painted the house white, inside and out.  I masked off the roof edges because I wanted to stain the shingles later. I then decided I'm changing the outside a bit.  So, I painted the areas that I may add stone a dark gray.  Since I couldn't find a tutorial on stones, I talked to a local miniaturist and she said use egg cartons and paint them. I started on the stone a few nights ago.
