could some one tell me how many gallons of water i should add to two pounds of black walnut hull powder to make a good cloths dye, i'm new at this dont want to screw it up...thanks

I have never used the powdered stuff, just walnuts hulls I get off the ground but I would start with five gallons of water. Boil the stuff up and let it cool before adding any cloth or leather to it.
Did you contact the place you got it from for directions? I would think they would be happy to help.

How fast is the dye for leather? In other words, if leather is dyed in walnut hulls, will the dye run if the leather gets wet?

I've dyed several hides in walnut-never had a problem with runoff...I would suggest a neutralizing rinse with baking soda or ammonia to kill the acid in the dye-works on cloth dyed this way also..Mitch

i dyed several items just recently useing advice i got here at the fire,used powdered hulls,soaked items in a vinager and salt bath before placing in dye bath,let soak for a couple of days ,rinsed in cold water then again in a baking soda bath.turned out great.

I boil up 5 gallons of water for 1 lb. of dried hulls. I make the powdered hulls up myself from whatever walnuts I pick up in the fall. I shell them and sit them in the sun to dry. Then pound them up some and store in bags for when I need them.

I have a big iron pot that I use. I fill a 5 gallon paint pail with water, empty in the pot and boil the water then add the hulls and bring back to a boil for several minutes to kill whatever living stuff, worms, bugs, bacteria, etc. is there. Cool it down a bit and add the material. I don't use any mordant for walnut but do rinse in a cold baking sode bath afterwards. Works great on linen, linsey-woolsey, wool, cotton, leather, etc.
