We attempted it before with a goat skin with "something" that my neighbour gave us (he's supposed to be a leather worker), but it ended up rotting and stinking the place out

If anyone can give me an idiot's guide, preferably with quantities needed then I'd be really grateful. And if anyone out there actually does this stuff regularly and wants to swap me a "tan your hide" kit for anything then please please get in touch.
