It was an easy project to do. I added landscape fabric for weed control and a 2" layer of sand before laying the pavers on top. I had to make two cuts around the post closest to the house. These cuts were made with a 4.5" angle grinder and a diamond blade ($10 from menards), and was really simple to do.
As you notice the pergola was also stained a solid black during the process. I used Cabot's solid color stain and I would recommend it to anyone that will listen.
