Chevron Pattern

I agreed to do a currently popular design called a Chevron pattern.   Unfortunately for me, I didn't know that I would not be able to use painters' tape with this new Sherwin Williams paint.  But before I knew this,  I tried using Frog tape to mark the points of the design.

These pieces were falling off.  So next I just pencilled in the lines.  

 I used a laser level as well as an ordinary hand-held level to get it exact all the way across the wall and the 45 degree angles.  Each diagonal line is as close to 12" as I can get it.  The height of each layer is 8"tall and 8" wide.
