Tiling always looks so easy when you see it done on a straight wall! But how do you do it with a crooked wall? Use a Measureright Pro to get the angle right. So if you've tiled from a straight right angle and you're just reaching the 'odd' shaped spaces between your last row of tiles and your crooked wall, you can use the tool to mark your final row of tiles so that when you cut them, they will fit right into the irregular shaped spaces between your final row of tiles and the slanting wall. The video shows you exactly how to do it and makes it look quite simple.
