Letting it "cook" is really important for me. If numbering and replacing everything is overwhelming, maybe you could pin the blocks to your bed cover and gently roll it up for the night and use something else to sleep under. It just needs to cook until you're happy with it. Maybe don't even look at it for a week or two. It will seem much less complicated after awhile, and you'll be able to look at it more objectively. It will be a wonderful quilt no matter how you arrange those blocks - really!
