A Fabric Mod to turn Rotten Flesh to leather.
I haven't found one so I made one myself. You get the leather by simply crafting it with rotten flesh. Furnaces were refusing to work for me so its a little primitive.
If you believe you know how to make it work or have an idea on a way to make it more balanced/better, feel free to leave a comment and I will try that.
I will try to keep it updated.
