First, nice tile!

Second, no matter what, use 100% acrylic modified thinset mortar and a 1/2" x 1/2" notched trowell.

It looks like your room is "L" shaped, right?

Find your longest run, place a large tile at both ends of that wall about 1/4" away from the wall.
Mark the far edges of the tile away from the wall.
Use a chalk line and snap a reference line on the marks where the tile was along the wall.

Using a framing square and a long straight edge or a laser do the same thing off the intersecting perpendicular wall.

Before you commit, check to make sure you don't have any sliver cuts ( under 1 inch )
If need be, move the layout one way or the other to produce favorable cut sizes.

I like to spray clear lacquer marking paint over my chalk lines so they remain visible during the install and it also keeps the red chalk off my clothes and shoes.


Let me know if I can offer any more assistance.
