The pattern shows as in the Pavilion Book edition per an Australian website.

editor’s note:
If you are looking for this in Harry Potter: Crochet Wizardry, please check the table of contents or full book before buying! Ravelers have confirmed this is not in the Kindle version or print version published by Insight Editions in August 2021. There is at least one other edition of the book with a different ISBN from a publisher in London. Whether the pattern is in that book has not yet been confirmed by a volunteer.
