Pumphouse Pinwheels

As you've seen in the last few posts, I used my Pumphouse alphabet to make pinwheels for a quilt.

There are 4 ways to make a pinwheel from a letter. This is demonstrated on the left using Z.

I decided to explore some of the possibilities.

Pinwheel

This grid is for a 48" x 72" quilt top. I want the center of focus to be where the black square is.

What if I fill the grid with 6" Pinwheel blocks?
