This book was not designed simply to be read, but to be worked at! The authors' suggested exercises encourage you to explore different design exercies; some of which you will find easy, some difficult, some boring etc. However until you try them for yourself you won't know which ones will help..... and it is often the ones you least want to do that bring the greatest benefits (I speak from experience). While both of the authors are textile artists, the exercises would translate well to other art forms and as you will probably already own most of the necessary materials, this has to be one of the cheapest design classes you will ever find .... as long as you are prepared to invest a bit of time!
