There is not much about collage that is not contained in this book. The authors begin with a short history of collage and how to make or find materials to make your own. Later in the book, they even explain how to make your own paper for collage and making collage "supports" or backgrounds using mediums, papers, and natural or found materials.
In an early part of the book, the authors delve into the collage process and give the reader eight projects (of varying difficulty)to try on their own. The directions and illustrations are VERY complete.
The next section deals with collage design, both planning and creating, along with nine projects that are, once again, carefully explained.
The section on mixed-media collage was very good but more for a person who has both artistic AND design ability. NOT ME!!!
Even though many of these projects were beyond my limited capability, I still enjoyed reading about them and looking at the beautiful illustrations. I got lots of ideas from this lovely book.
