Overthinking.

So I finally started to work on my Pa Dutch BOM. I started with this block: Sorry for the small pic but I clipped it out a jpg. I cannot get my points on the pinwheels to match nicely. It is driving me crazy. I made one pinwheel and sewed it to the other squares. Then I made another one and ripped it out.

And ripped a hole in it.

Am I over thinking this?
