The book is a beautiful collection of ideas and methods, with good quality photographs to show you how to achieve the end results or your own variations. As well as ordinary techniques,
Gwen's keynote is how to turn junk into beauty - many of the ideas involve "found" objects and waste, and items we wouldn't normally consider using. My only quibble is that the format of the book sometimes seems to override the content, so that every idea is presented in the same way; however, there is such a wealth of invention & variety here, you can't really complain.
