Will have to reread that part of the book
It does say so ... when I did the course, I had prewashed before I knew so. I asked and the teacher said, no problem, just starch it up good. There is the risk of it stretching some, though in her view, the non-wash or starch lets the fabric slide better on top when you are stacking it. Plus it helps stabilize the bias cuts and minimize fraying.
Even if you do pre-wash, you will still get the wrinkles when you wash the quilt. The 80-20 Warm and Natural estimates about 2%. This fabric would have been 6.7% ... that's a lot more wrinkles.
As I said, whatever works for you ... works!
