I contacted Jenny Bowker (The pattern designer/teacher) and she is going to teach a class at Empty Spools in Osilomar, CA in 2014. She currently does not have the pattern (Sparkle) for sale but is considering it after seeing the response to it. Also her book is not ready yet, but she put me on a contact list to be notified when it is. If/when I hear more I will post it for you. You might also contact her on her website and let her know that you, too, would like to buy the pattern.
