You have a gift in that you can look at a pattern book and envision fabric you have access to.
I have a hard time looking at a pattern and figuring out what it might look like with fabric in my surroundings.
That sounds like I am making excuses for not really looking at that book, doesn't it? LOL Bummer!
I think - - based on the photos that the darker pink inner border you were mentioning would really make that quilt look elegant.
I think your first instincts are pretty good!
