My son brought home a stack to make a Halloween costume. They smelled horrible and left that "hair" and dust all over the kitchen. He didn't try to wash them. Not sure how he could stand the smell to wear it. He said it smelled, was stiff and itchy. He threw it on the burn pile when he got home but kept the hood. Just to say he made it himself. After reading youngduncan's experience, I'm so glad he didn't try to wash them.
