Day 3.. Filled in the right side of the panel and did my cuts for the row above the panel and joined them up. I couldn't have got it any more level than I did. No shims or anything needed. It just worked. All that time making sure the framing was dead nuts and the countertop was perfectly level paid off.

I was initially going to let the stone hang over the edge of the top of the panel, but decided I wanted to "frame" it like I did the sides.. Not sure how I'm going to do it but I'll figure it out later. Right now I want to get all the stone up before dark.
