Lay out the tiles: After you've found the center point and squared the room for floor installations (or determined the top line level for walls), lay the tiles out to see how they will appear. Do it dry, before you mix the adhesive or mortar, within each quadrant of the grid.
Once you've identified the center and baseline from which you will work, snap a pair of perpendicular chalk lines. These will divide the room into roughly equal quadrants. You'll want to work outward from the center point in each of the four sections.
