Artsyone- I like that a lot. Youkve got most of your big elements chosen and once you’ve decided for sure where you want them to land on the quilt all you will need are the filler strips to make it all fit. Have you been taking photos each time you rearrange it? That's always helpful for me. Also when you take pics of an arrangement be sure to use the edit feature to put them in monochrome so you can clearly see any place that might need lighter or darker values- that’s another trick that has helped me when I’m being stuck.
