Walnut Dye for leather

[Frazer harris]

Afternoon all,

So little project I have given myself for the winter, been reading up on dyes for leathers come across walnut shells for making brown leather. So not sure I could consume enough walnuts just to have the shells for the dye but have found crushed walnut shells used for lizard/reptile habitats. Guessing these would be natural due to the use they would be needed for. Just wanted to get peoples thoughts on this subject.

Many thanks

Frazer

is it the dry shell or the wet husk you need? Usually its the wet husk that stains everything it touches brown for ages
