Use the 12" tiles. Run a joint at center. A full and about an 8
1/2 border.
head slap I had considered that layout at the very first, but
rejected it to try to use full tiles. For some reason, I never looked
at that option again after the unacceptability of the thin tiles was
apparent.
That is the easiest solution.
Run the tile on the 45, place diamond at center. Diagonal will be
17, 12" border.
You mean like so:
