Find where to start when tiling easily using this simple method.
Firstly you need to find the center of the wall or floor in each direction. So on a wall the center of the width and height, on a floor you need to find the center of the width and length.
Then once you’ve done that you need to get the tiles that you’re about to use, mix up the boxes and tiles so that you have a few stacks of mixed tiles. Each stack using a random amount of tiles from every box.
The purpose of doing this is to ensure that all the tiles you’re working from are randomly used, rather than using one box, then another, then another, then another, which can cause your size tolerances to be an issue if you find the first boxes were thinner than the last boxes, your spacer gap disappears.
Then what’s next? You sort of stopped right there.
