I had it laid out on the bed most of the day and went to look at it and muttered to myself. Sort of like Hattie MacDaniel in Gone with the Win (Mammy) it ain't fittin' it just ain't fittin'.
Ultimately I have decided that although I would like the proportions better with a narrower center strip in my border, the reasons I went with the larger block sized border is it makes it a more useful quilt size. I'm going to go ahead with it as is and be glad that it isn't for anyone in particular.
There is always next time for a chance at some sort of perfection.
