You’ll see in the pics how I had to first lay everything out, cut what I needed to, place the whole puzzle on the floor, spread mastic, and put it all back together.
I quickly learned how difficult it is when the surface you’re tiling is not perfectly flat! Add to that, the fact the accent tiles were about half as thick as the black granite and it left me with finding creative ways to figure it all out. I used extra mastic, washers, cement board, and whatever it took to get the accents as flush as possible.
