work in progress 9 Patch

I  have taken a break from this piece over the summer.  I am designing as I go.
Today I went back to it and have started cutting some new 2 inch squares from my scraps.
I am committed to creating scrappy quilts and I like to get as
many different patterns of fabric as I can which makes for very fussy cutting.
Seems that I am working with the interplay
of dark and light and a 9 patch cross unit.  I can not plan ahead not in my DNA.

Here is the new square I made yesterday

2 inch squares

Nine Patch fragment

I have connected it to this square with these two blue 9 patch squares

I have two other squares that are different from these
now how to use them.
