Hey I have buckstitching on my saddle and think it looks wonderful! And I don't have all kinds of silver to have to worry about cleaning and keeping shiny.
I make custom a lot of belts and at least 30% of my orders are for buckstitched belts. Not all are white, I also use cream, two tones of brown, and black! People still like them and look for them but are hard to find anymore. See the work at http://www.garyscustomsaddleryandsilver.com
