I woke up at 3 am and the first thing to pop in my head was pinwheels! :D
It dawned on me that using 5" squares in the draw the line method would end up with a 9" finished square which I think is perfect for my project.
Using 5" squares with the sew around the edges method, the finished block would be only 6". Not the perfect for me 9" size I was thinking.
I looked up this chart I had seen on here to calculate the finished size block for the sew around method and thought I would share.

If you double the second number in the chart and subtract 1" you get the size of the finished square. (according to my calculations)
Luckily for me, the blocks I am using are 10" right now so if I cut them to 8" instead of 5" my blocks should be my perfect 9"!
As of now, I will be using 8" blocks in the sew around the edge method and making the quilt 9x8 blocks and then maybe a border or two!
All this is subject to change of course!
:-D
