Jody,
Thanks...yeah, I realize that some of the seams are a bit long. Definitely something that I will pay more attention to on my next project. As far as the thinner pieces closer to the end, I actually did that on purpose, as I liked the look over a longer continuous piece trimmed on the edge. I guess that's a beginners error there

...no other excuse except for that!
I appreciate the tips and any advice anyone might offer on making the next project better. I am pretty pleased with how this has turned out for my first try, and I have a long way to go in getting really good with the natural cleft stone (tested my nerves more than once during the laying process!!!).
Thanks again!
