I believe she was correct in saying it was rarely seen as I have not been able to find any examples of this quilt. Maybe it was known by another name also?
Since this is an applique pattern, I did not try to make it for my sampler quilt of 6" blocks.
Nancy's pattern for the Kentucky Peony quilt can be found here.
If one was trying to use her pattern, it might look like this except she says to use only eight blocks but set diagonally with white squares. I'm not sure how you would only use eight blocks.
