Radiant heat floor mats laid- these are what gave me so much trouble:

I will come back and post a finished pic after I lay the edge pieces and grout!

ETA:  Here it is!  Unfortunately the grout is drying far too light- it’s supposed to look like the grout in the center of the picture, but it’s drying like the grout on the far left.  :(
