Our tile installer told us to use 1/16" grout lines (instead of 1/8) for our Encore Bravo Crackle backsplash. They are already halfway done and I am in a panic. Luckily our grout color matches the edge of the tiles. Will this highlight the variations in the handmade tile? I am afraid it will look crazy/messy. I am also concerned about lippage and settling.
