Because I didn't follow my design correctly, I had to pop up two tiles. It gave me the chance to see that I've done good work. From what I've read, tiles should be 80% covered for residential and 90% for commercial, and of course closer to 100% is ideal. I haven't done grout, which would have filled in some of the edges, so I'd say this is at least 95%. Pretty good for a far from pro.
