Using cushing acid dyes- this was on medium brown which gives a great Auburn .The basic directions are the same for all colors
Here are the directions I have for the dye . Allowing it to cool in the dye bath is very important as some how it comes out more even. Also there must be plenty of room for the dye to move around the fiber And the fiber must be free of lanolin for the dye to come out even.
I use 1/8 tsp per oz for a medium auburn ( the center color on the auction) ( YES I know it says brown but it comes out auburn on mohair) Use more for a darker auburn less for lighter the lighter shades are more golden red toned ( like a blondish auburn) and more will give a deeper richer color. be sure the mohair is very clean and for the most even colors you should leave the fiber to cool in the liquid. These dyes are easy and so much cheaper to play with than hair colors. I rinse with clear water after dying , then a bit of a hair conditioner and lightly rinse ,and it comes out so soft and shiny.
Do not leave the dyed fiber soaking in hot water too long especialy with fabric softener or hair conditioner . I found out this can open the fiber scales and leach out some of the color.
