You seem to be sussing out scallops etc well - I did consider doing mine in one long length, but opted to seam the sections so that I had a point of reference to join them to the border. In the past, I have had one or two quilts that the outer edge always seemed a tad too short which really annoyed me.
I got my AOTH book today, and I have to say I really like it. I have no doubt at all about being able to upsize the blocks, and those of you thinking of being able to machine applique, that would help, wouldn't it. (My personal problem will be that my printer is playing up at the moment and I might have to buy another).
The quilt also has three narrow borders cut from a border print.... next question, where would you begin to look for a suitable one? I have just been through all of Jinny Beyer's site as she was my first thought. I'm very disappointed - so many of them were out of print, and those that weren't didn't seem to lend themselves to this quilt.
