@hawkeye10,
The layout has to be much more straightforward than that due to space. Each letter has to be a minimum of 7 tiles high, and 6 tiles wide (with the exception of "i"). The uppercase "W" and letters like "h" and "g" have to be 10 tiles high. The grout between the tiles will add about another 1.5" - 1" per letter. Then there's the space between the letters, so an extra half inch per letter or 1" -2" per word.
Since I only have a 43x40 space to work this into the words have to stacked on top of one another.
I tried working out about 5 different phrases before looking up Latin phrases to see if I could get one to work out better. I couldn't. Even with this phrase I had to switch to .5" tiles which left enough room for a boarder, should I choose to use one.
Trust me, I've looked at this design problem from a lot of different angles.
And I like things to be properly punctuated. That means there is a period at the end of line four which balances well with a punctuation mark at the end of line two.
