Wow, don't you just find it impossible to think of anything else when you have so many options? I'm sure you're wondering where the time is going...I get so overwhelmed and look up to find that someone has fast-forwarded the clock! LOL Okay, your quilt, your choice...but I'd try running the cool colors in one diagonal and the warm colors in another diagonal...just to see how that looked. Somewhere I read that having a "rule" or two can make all the difference in organizing. I applaud you for wanting to make the most of your blocks...your work is beautiful!
Oooooh...just saw the last photo...and if that is just tweaked a bit as I mentioned above...I'm going to believe that it will be GREAT!
