What's your tiling method?
I set a level ledger board one full tile-height from the floor. Since my floors aren't 100% level I start this midpoint so I don't have bizarre gaps where the tiles are too small - I'd rather have them snug, just right, or trimmed at the bottom.
I always start in the center of my area and work left them right with full-size tiles, I save all the cutting for last except for tiles that need to be fit around plumbing and so forth.
I start at the bottom of each tile row and work up - I never do from the top down. I did that once and hated it, the tiles want to sag. Little strips of tape don't outdo gravity - and it was a nightmare.
At this present moment in time I am making cabinets for the kitchen - just in case you wanted to know what I'm doing when I'm not around.
