Mike, I used two coats of Fiebing's Pro Dye Black applied heavily with a wool dauber. After drying, two coats of Skidmores all of which I had to(?) apply before the spots and conchos. Just gum tragacanth on the edges.
This was a lot of fun and I believe I will try a few more. I tried to work slowly and kept in mind something I heard Purdy Gear say some years ago when asked about her work, "I sweat the details". Now I know how much work you guys put in on each job!!
