So back in the day when I was in art school, I would make my own wood stain in order to get the colors I wanted for any given sculpture. I figured I would play around with the same homemade stains for dying some feather. And I thought you all might enjoy it. The pics pretty much say it all. Just mix an oil based paint with some thinner, I used acetone just because I have some already. Mix it about 60/40, 40 being the thinner, and brush it on. Twenty minutes later, I'm done experimenting and you can see the results for yourself. The best part is by the time I finished all the colors the first ones I did were dry.
