Shopping List for Leather Dyes

So the other day I went through the recipes in my leather dye book and sorted them into categories. There are some that I'm not going to try to do, either because they use ingredients that are toxic, super expensive or the yuck factor is just too much (yes, I know using urine is period but I'm just not going to do that - I'm not that hardcore).

However, I still have a good handful of the colour recipes that I can do fairly easily. I haven't gone through the black/grey ones yet.

I'll need to do some research on where I can get the ingredients I need, but for the time being, here's my shopping list:

Ripe buckthorn berries
Roche alum
Brazilwood
Gum arabic
Live lime
Indigo
Alum of lees (??? maybe substitute Roche alum from other recipes?)
Litharge of gold
Walnut oil
Curcuma
Woad
Sweet lye

Some of these will make duplicate recipes. So, for example, the ingredients listed would make two or three different blue recipes so I can compare and see which one I like best for specific purposes.
