My first headstall, when I finished, I found there were a lot of questions I should have asked before I started..I used HO 8 oz and lined it with a 6 oz leather that I picked up from a friend who got the side in Brazil. It seems to be heavily waxed and tallowed. It has a beautiful feel and finish.
Do I need to oil the lining? The headstall is hand sewn with linen thread. If I oil, will the thread deteriorate?
