Morning all. I hope everyone is well. So back to setting out my tiles dry on the floor and have discovered the floor tiles will not be able to line up with the wall tiles as the floor tiles are 2mm larger. Which is fine. A question I do have though is that how do you level the tiles horizontally and vertically if they have not straight edges? Do you actually use spacers for non rec tiles. Do you level the highest spot on the top of each tile.
