I knew it only because, like you, I read the book. I'm interested in the history of Dear Jane, as well as, the quilt itself. Jane Stickle made her amazing quilt without the fancy tools and notions we use today. I think some of the people on the other thread didn't like the book and instead wanted precise patterns to follow, but once they start making the Dear Jane blocks, I'm sure they will find the book very useful.
Have you made any blocks, yet? I'm finished with Row A and the first couple blocks in Row B. I'm trying to make my blocks as much like Jane's as I can, except for the size. Mine are all going to be 4 1/2" finished.
