So I hit 30,000 pelts/hides and I just couldn’t get rid of them fast enough.
So I spam buildings that use them to make stuff.
now I’m swimming in coats and shoes. I have 10,000 shoes.
Did it help my over abundance of pelts/hides? Sorta I’m down to 27,000.
At least it is no longer growing in total lol
Store them in a storehouse outside your walls and maybe the raiders will take them. It’s cold out there.
Now that’s sounds like a good idea to deal with raiders. 
Gruff voiced raid leader, “40k gold or we attack!!!”
Villager “we have fur-lined Alexandrian leather coats, and Khan shoes that are all the rage. Will you take these for payment?”
Raid leader, eyes softening a bit, licks lips… “are the soft?”
“Yes!”
you think you hear a stifled giggle escape the leaders lips
“OK” he says excitedly, then a bit more gruff “and that is TWO for each of my raiders!!!”
