Query: Disappointing

I was so excited to find this book. The designs are gorgeous. The patterns, however, are useless. While I consider myself an advanced crochter, I have had to repeatedly re-do and modify all of the half dozen projects I've completed from this book. I am convinced that there was not a pattern tester involved in the publication of this book. At best, this book is useful for inspiration. At worst, it is frustrating to put a lot of work into something and not have it come out right. I would like to see this author and publisher clean these patterns up and issue a second edition. Until then, I wouldn't bother.
