Update note 5/26/26: This book is very difficult or impossible to get. The author self-published it and doesn’t seem to be shipping it any more even though the website says she is. I recommend looking for a friend who has it or a used copy somewhere. If I hear that someone else is selling it, I’ll update this post.
I recently purchased Mette Lise Rossing's new book, The Thread's Course in Tapestry. It is a wonderful reference book and I definitely recommend it. Here is a video blog segment about the book.
