Great job Debandi. I never seen anyone trace a head stone like that. Creative idea to say the least and to be able to carry it back with them. My Dad was a big geneology person and I remember going to many a cemetary with him in the 70's. He would take pictures of old headstones and some were hard to read.
Just for the picture, he always carried a big piece of chalk, like the kind that kids use for drawing on sidewalks. He would turn it sideways & run it up and down the face to make it stand out for the photo. The 1st rain would just wash it off.
