I recently bought some natural paint pigments from Crazy Crow, to try to make some parfleche and to decorate some rawhide sheaths I made. I got the pigments, but they do not come with instructions on how to mix and use them. Can anyone tell me what to use to mix them (water, oil etc,) in what ratios and the best way to use the pigment? Also, what is the best way to seal it to protect it? Thanks!
