I set the back tile very tight to the wall. This is the center 35cm of a 30cmx60cm tile.
We cut the left and right edges off and selected a tile with some nice veining at this section so we could roll the corner.
Before setting these tiles I placed the tiles in position in the clients living room and send him a picture and video to review at night after his meetings in Montreal. I heard back the next day that my selection and placement met with his approval.
This I find gives a client great piece of mind why travelling away from home. You can be part of a renovation but without the noise and the activity on a daily basis.
