I am deconstructing an old saddle of mine. First time, no help but what I get online. Are there tricks to removing the tiny nails that are in old thin leather without tearing it? Also, my saddle's skirts are sewn together. I was advised not to cut them loose and just take it apart together. Since I have never done this before, I don't know if I will be able to really clean and condition the leather unless I cut them loose. Any advise?
