Lessons learned.... The hard way.
Also, never talk your spouse into using another product than the one he's had luck with in the past just to get a job done sooner. Though it seemed to work just fine at the time, it wasn't long before one of the tiles cracked.
After hubby carefully removed all the tiles we took one with us and headed to HoDe and L's. We were very lucky to find a marble tile that coordinated with the originals since the original tile was no longer available.
Once home I scanned both tiles and used the Paint program to play around with patterns. The one you see on the right won. #lessonlearned
