I am brand new to leather work. I am very interested in this topic. I had a pair of boots made for me in Europe (alpine mountaineering boot with cleats and hobnails) and I am in the process of dying them. I used a deglazer first to remove the existing finish on the leather and I have put one coat of Fiebing's Professional Oil Dye in light brown on the boots. I am trying to accomplish a very lighter brown color. I have used Birk 4 a lot in the past on other boots I own and have a large 16 ounce bottle. Can I mix the Fiebing's Oil Dye with the Birk 4? The reason I ask is that the first coat of Fiebing's Oil Dye left the color uneven, except the tongue of the boot. I am hoping to even the dye this morning then work the Birk 4/Fiebing's Oil Dye mixture into the boots to get the even color I am looking for in the finished product. I can send photos if that helps.
Sorry I typed incorrectly, I meant Bick 4!
