Query: Disappointed

There are some good ideas in this book, but many projects were not completed with a few simple sketches or explanations. Also too many of the projects were useless ideas. I also bought one for my daughter and she came to the same conclusion as I did. She said "Dad I think you wasted your money".I think a thoughtful rewrite of this book would make it a winner as both my daughter and I have seen many other good uses for PVC pipe.
