Sharon, what you have is FINE! Go to the Show & Tell/ Show BOM only, and click on Sue's finished quilt. It's the very first one in the gallery. If you click on it again, you will get a larger view and you can see that one of the things we will do in March is add another floater strip, and you can make any necessary changes there! No big deal!!
If you will also click on my finished quilt (the third one in the gallery) and compare the widths of the floater strips, you will see that the one on the outside of my pinwheel border is much wider than the one in the same position on Sue's quilt.
That's the beauty of this great design. We can all make adjustments to make things fit together, depending on what size they turn out!
Kool, huh?
