I just started to dye my deer tails for tying bucktail jigs,I use veniards dye.A lot of the tails are whats left over after using the Chartreuse, yellow,blue ,orange and red,I dye them black they come out like a bought black tail.I also clean and process around 150 tails in the fall that I get from a couple of abattoirs in my area for free.I dyed some orange and yellow they turned out excellent also.You only have to use 1/4 of a teaspoon to 2 pints of water and 3 tablespoons of vinegar to set the dye,that will do about 8 deer tails.
