Please keep an eagle eye on her website or blog or whatever for corrections!
I took a class taught by a certified JN specialist, bought the pattern and the fabric, read the pre-class instructions, did everything my LQS said to do to prep, followed the printed pattern instructions to look at the website for corrections, downloaded the corrections from the website, and still got smacked with pattern errors which had to be corrected in class by the instructor. Things like - the numbering on the PP to be followed is wrong, so every time you see a "2" make it a "3"...It was a beautiful pattern, I picked great batiks, and I will finish it someday when I sort it out.
I am sure you will make a simply breathtaking quilt as those patterns are stunning. Good luck! there are many JN addicts on the Board who can assist you!
