You might find that once you've reached the end of your first row of tiles you might need to cut one, so it fits into the space near the corner. To do this turn the tile upside down and lay it next to the space where it will be laid. Mark the width of the tile you need, remembering to take into account the gap that is needed between the tiles and also the tile and the corner wall. Place the tile into the tile cutter, making sure it's square, run the cutting blade along the tile and apply pressure to break it. When you lay this tile, put the cut edge closest to the corner.
