that's how I am being taught to do it stef so have no choice on the matter mate lol. but tbh I just mark a few course up, strike a line around the room and then work down from that level... then when it comes to chucking the screws into the wall you just have to push the tiles together (with the spacers in place) if ya know what I mean mate? its very effective tbh
I only do this when needed but you would be quicker to stick a batton on the wall Ash,
Depends how heavy your tile is also..
