This is the back. I stitched in the ditch around all the pinwheels. I pre-planned the horizontal and vertical paths which made the quilting proceed quite smoothly.
I wanted to use up the squares that were leftover after cutting my pinwheel blocks, so I worked them into this border. But! The twister is so complete without additional borders and next time, those leftover squares are going back into my scrapbox. There are plenty of patterns which call for 3-1/2" squares.
There definitely must be another twister quilt in my future! It was just a fun time.
