Laying out tile with random veining
I'm wondering if any of you have ideas about how to lay out marble look-alike tile (and these ideas could be based on natural marble as well, obviously). I have 12" square tiles to be laid on the floor, on the diagonal. Many of the tiles have veining going in biggish streaks across the tile, or across the corner of a tile. I assume I should avoid a situation where those streaks line up, but maybe I'm wrong. I'm afraid that having the veins go the same direction would look like I was trying to replicate a whole piece of marble, without success since the veins will never match up. So my hunch is that I should allow some to go the same direction, but to turn other tiles the other way.
How did you do it?
