Then I asked:
What if I replaced some of the squares in the ninepatch block with half-square triangles?
What if I use this block in the corners of my quilt?
What if I use this second block on the sides of my quilt?
If I do, then the result is the quilt that started this post.
But now I want to explore other possibilities.
What if I then repeat this new block?
I have to admit. I like playing with ninepatch pinwheel blocks. I'll probably do another one tomorrow.
