I saw another pinwheel sampler that put block #7 in the four corners and I liked how it looked. But instead of making 4 of the same block I switched up the pinwheels for block #8. The borders are the same size as block 7 except the outer-most white border. I ended up making the pinwheels too small so I made the white outer border 0.5" bigger to compensate. Other than that it turned out great!
Now all that is left is to sash it and pick out the backing, then it's off to the quilters! :)
