Chip, what colors did you use on your wall and mortar? Did you paint before you installed the walls? Very well done.
Art: Thanks for your paint colors. I may try working on this soon.
Here is what I used:
Behr paints:
Sparrow

Gentle rain
Craft paint:
Flat black and mixed it with gentle rain to get the darker color.
I painted first. Used a # 2 pencil eraser to give the stone contour.
Something to help make the alignment of the coarses go fast- I had a piece of 1/2 " aluminum angle that I used once I got the first coarse squared and lined up I could place the angle right into the groove and set the next coarse and cut it with the razor then follow with a blunt pencil and then put the angle in it and repeat. I made 3 sheets in about 6 hours
