I want to change a pair of mid brown shoes to a mottled blue/black Lobb Museum effect. My plan is to acetone them, dye them with an aniline blue dye, then over dye with black and use alcohol/bleach to lighten toes and heels. Condition, cream and polish. How hard can it be My question for the members of this august forum is what is the best type of aniline dye to use? Tintex? Are there tricks to ensure I get the right finish/effect? Any help is appreciated.
