Carrie, I am sorry to say that the book does not tell you but I can tell you that I started with 6 yards of my focus fabric. Some stars took more fabric some less. I still had a yard left over when all the blocks were done but I did use it in my border. And I did make 6 extra blocks. I believe the one that had the background fabric all the same needed 6 yards also. It is a guessing game. Hope you decide to make it. In the end you will be glad.
MonaLisa, I hope you find someone who will love your blocks as they were all beautiful and I would hate to see them stashed away forever.
