@lyndine2009 I imagine if you had a magic storage box and lived alone in the woods with no means to buy or barter you would hoard all the materials you found, no matter how gross. Also, if he has had cleaner smiles for a while, he could always clean the cloth and then repurposed it.
I know there is also the japtem inventory thing in games, where you collect drops mindlessly irregardless of whether they are useless or not.
