I made a mistake but cant figure out how to edit. The third paragraph should read:
Anyway, I'm not sure how to set the pattern with that weird little space to the right of the bench on the back wall. It's 18.5" tall and 29" wide. Since the first row will be 7.5", I can fit a row of that shortened tile, a row of regular tile, and then the next row on top of that I'll have to take off a corner when it hits the bench. I'm not sure how I'm gonna do the 1/2 overlap there, though (since it's 29" wide and two tiles are 24" wide).
