Option 5 won out. Sort of.
After an evening of doodling/sketching and staring at the layouts, Hubby and decided on a wilder pattern that was only indicated by Option 5. So I set up a temporary design wall by taping batting to a beam, put the sprinkler on (and the TV later) for the girls and I spent the afternoon working out the puzzle. After the girls were in bed I picked up the mess made when my youngest (aka Evil Genius) purposely walked through the hanging batting and Hubby helped me finish the puzzle.
(don't ask me why my winter slipper is in the midst of that when this was taken on the hottest day of the year so far.)
It was a fantastic, contemplative exercise. I definitely picked the most complex of the options. Not because I like to make my life difficult, but simply because that's what spoke to me. I could happily have made any one of the quilts, and likely will at some point. Thank-you for all of your opinions.
And maybe, just maybe, I would love to keep up the design wall... It looks good from the front and back.
