Believe me
I'm sorry, I don't
Just because, to my char, each creature whose hide she's working with is valuable/important exactly the same
Also, I asked because it'd be good, for me, to buy (and work with) terrible, cheap hides bought by newbies instead of precious, expensive hides bought by older characters. And my character too, she'd rather buy cheap terrible hides sold by 'poor' people than perfect ones hunted by more skilled hunters.
And it'd be the same if, for example, it meant a lower quality. Just a choice, nor right, neither wrong
Anyway, I thought that what I was asking was 'easy' (but perhaps it isn't) simply because it's only about already craftable things.
