Tanning Rack

You should add a tanning rack
Like the thing you use to turn animal flesh/hide/skin in to leather
And you could use rotten flesh from killing zombies to make the leather (to put a use to the rotten flesh)
And you would use like 12 rotten flesh to make one leather or something
So then a stack of rotten flesh gives you 4 leather

and i have come to the realization that this may be a mod already but you should add it to the vanilla version of the game to put a use to all the rotten flesh one may acquire through just normal gameplay and having to kill zombies
