when you do the laundry for him, you get the opportunity to steal the cloth. you get to do laundry at torben's house in bareshade, it's an option among other chores you offer to do for gunnar.
hmm, it's possible gunnar has to like you enough? i'm at 63 with him, so i didn't have any issue finding the laundry option. that's all i can think of though, sorry..
