Hi everyone! this is my first post to this forum but I've been following it for a while. it seems an appropriate thread to add a question. I got some (well, quite a few) leather scraps I thought I could use to make leather bags. They are white, varnished on top side (though I plan to put the under side as out). When I painted it with Fiebings black dye, even after a few applications, it keeps a metallic bluish tinge/hue. I've noticed this also before with other projects. It stays even after applying Resolene or Leather Sheen. Would anyone have an idea how to get arid if that? Oh, I did try the vinegaroon that I've made for the first time just for this project and it doesn't react. It works perfectly on veg tans I tested it on though, so the roon is good. I'm currently soaking one piece of the white leather in tea. I was thinking, Maybe if I manage to get some tannin into the leather, it will react... At least a bit. I'd still appreciate any opinion or idea. all best!! ps. This is one test piece that I've made from that leather. Not sure if the blue tinge is visible.
