I worked on a project over in the Whitemarsh Maryland in Nov 2010. This Youtube is just a simple kick back uncut. Just over 5 minutes. In this footage I'm working on the corners. The corners can be some of the hardest areas due to the fact your trying to tie in. If you take your hands and put your fingers into your fingers. They then lock together. You will see some of the challenges one can have when working with stone. I was running out of good corner stones to work with. Forcing me to shape stone to get what I needed. But in the process you always run the risk of loosing a stone. As seen in the video. Enjoy.
