That quilt is lovely and I wouldn't change a thing.....but what I have learned in my years of quilting....IS stick to tried and true patterns.....my imagination doesn't transfer well to the pattern..my quilting partners use to say.....why do you invent a pattern when there are perfectly good patterns out there that WORK!
That being said, the pattern is amazing and it looks great...square it up, quilt it and call it a day!!
