Wow, Macybaby you are very organized. If your 'machine shed' had the stars all around in one row it would be similar to a fancy Victorian wallpaper treatment where there is an 8-12" complementary border print or stripe right at the cornice. I think that would look really cool and because of how you did the stars so color-coordinated it would tie the room together.
I am getting nervous about the finished product - although I used all leftover batiks and I am repeating fabrics occasionally from block to block, it's a LOT of random color in one quilt, not in my comfort zone. I wish that I had done them in 6". Maybe I will call it done when I am at 25-30 blocks. I think that is more than enough real estate.
