I know that many of you are interested in recovering your older rangefinders, especially you FSU photoapparat fans.
I have been gathering information about materials and stumbled on the following site-
Talas is a bookbinding supplier that carries leathers, cloth, other materials and tools for the handmade bookinding community.
You can find Some very nicely finished goat skin in gloss and matte finishes with fine thicknesses that might be suitable to wrap your old FED or Zorki. The prices shown are by the square foot, but they only sell full skins. You can find listings for 2nd and 3rd quality skins.
I also found some really nice paper-backed Japanese silk in a variety of colors. The textures looked very attractive.
They also carry double sided adhesive. Or you can order a nice thin one from John Goodman.
