I laid out the curves on a piece of plywood about two foot wide. Then cut it out. Then you can sandwich the pvc pipes between two pieces and it looks like it is running through a solid piece of metal. Later someone pointed out that I should have cut spacers to place between between the plywood on either side of the PVC pipe and it would have hidden the work a bit better.
The color is sort of a personal preference but I feel like if you look around at what color most stone is in your area it will give you a good place to start. Most building material (particularly from old graveyards) uses the local stone. We have quite a bit of white stone in the area so I went with strictly white drylock. I love the texture and it is easy to age the white background.

My love, sweet Queen and noble wife. I alone remain to bring delivery of your pain. Severed my darling, too quickly from this life. Of fires drawn and memories met, I shall hold our two hearts again in single time.
