I have been using a wool dauber to apply Fiebings on my sheaths. Works grat for black but the brown comes out too dark. What is the best way to get a lighter color? Am I getting too much saturation?
I have noticed the same thing when using the wool dauber, but packing 4 cotton balls together in a scrap of tee-shirt and tying it shut worked really well for me to get a lighter brown.
If it is alcohol based dye, you may want to try cutting it with denatured alcohol. A lot. Obviously, try on scrap leather until you get the effect you want.
Also, if you have an air brush, you can feather it in with some practice.
