I’m doing white. I want the tiles to pop. When I told the tile lady I wanted white grout she said, well, we’ll have to see what your plaster color is. My thought was, no, it doesn’t matter what my plaster color is because I want white grout . I emailed her last night about some things and confirmed I wanted white grout. When she wrote me back she said, I want to confirm that you want white grout. What the heck!?! YES! I’ve already told you that . Twice! But you’ll need to decide if you want to see the individual tiles or want them to blend together.
