Setting triangle progress

I have the 3 rows at the top right and 3 rows at the bottom left sewn together.  I need to add 2 more sashing strips and sew those 2 rows to the others and then I'll be ready to cut corner triangles.

Here is a close up of the setting triangle fabric.  It is one of my least favorite of all of Kaffe's fabrics, but it sure is perfect here.  Someone without an email link asked yesterday how I knew the setting triangles should be a brown print.  I knew it had to be a neutral color and the only 2 neutrals are brown and grey.  Any other color would have just emphasized that color all through the quilt where the brown can just be sitting there like a background and not draw your eye to any specific part of the quilt.  It is all gut feeling/intuitive for me.  I don't follow any rule book.
