Foldforming is a metal technique that can be used with or without enameling. The "father" of foldforming is Charles Lewton-Brain who wrote the project in the book. A simple set of line folds are used in the project, but the chapter provides examples of many complex folds that would be great for enameling. A specialize form of Foldforming is called Score and Fold which can either be freeform or in patterns. Another type of specialty Foldforming was done by Harold Tishler and a mini-project on one of his patterns is provided in the book. Below is more information on Foldforming.
Charles Lewton-Brain has many videos on youtube.com, some about Foldforming and some on other metalsmithing techniques. Charles also sells CDs and many books on a variety of topics. Others also have videos on youtube.com - just seach on Foldforming.

Class with Charles Lewton-Brain
Just had a class with Charles at Peters Valley and it was terrific. He teaches at many places so check your nearest craft center to see if he's scheduled. We learned tons of folds. I made this bowl on the 4th day of class. Mmm now need to decide if I enamel it or just add a patina. Charles does sell a book on patinas for metal finishing.
