Pinwheel Fun

Back in April I asked all the Peace Circle ladies to make me 2 pinwheel blocks.  They could be 3" 6" or 9" (finished).  I thought it would be fun to piece together different sizes that mathematically could fit together.  It's on the smaller side, but it turned out really cute, and I added a border to help out with the size.  I really like the 3 different sizes.  It adds a bit of interest.
