As I tend to work mostly in a studio setting with lights, I use a coated fabric that is 100% light proof to a flash gun. If coloured bellows are required (Bright Red and Royal Blue have been the most popular!) the lightproof layer is on the underside. The completed bellows are usually about the same thickness as the original.
Details and examples here: http://www.sandehalynch.com/isolette.htm
As there is such a a wide variety of shapes and sizes among the older wooden cameras I would need to have the original bellows in order to make a copy. However, if you only have the frames I can design a new set according to the extension required.
