I really love the patterns in this book. The eBook formatting is really well done. There are examples of colored patterns next to a black and white version. At the end of the book you can get the black and white version in pdf format. I love the examples - they are fun to see and make it worthwhile to also have the Kindle version. I do not like that it forces you to sign up for the newsletter before accessing the pdf version. I would have gladly signed up anyway, I just do not think forcing people is appropriate.
