kitchen tile going down soon

Well we are finally  placing our tiles down on the kitchen floor. My husband is VERY particular  so we lay them all out to make sure the tiles look right together. We have really liked using Ditra board by Schluter. It is so easy to work with. That's  the orange  grid you see under the tiles. We are using Noce

 Roman stone. We are doing a staggered pattern with 18 inch and 12 inch tiles. Can't  wait to put it down  permanently.
