I don't think I explained it properly,
When you know where your middle tile is going to go (which you should have drawn a straight line)then move back toward the edge before the cut edge tile,start your full tile from there parallel from the middle line,so it doesn't matter where you start as long as you have done your layout plan correctly.Like I say there is no right or wrong way of doing it.I find it awkward starting in the middle then start leaning over and where to go next ! I've learnt this from a professional tiler maybe the reason is the less he have to move the better,if you think about it you're only moving one way and you can keep using the straight edge as you go along.This is only for tiling the floor and not the wall.
