I've never had one until recently. I think they're an amazon place to store towels and bedding. And I put bread in there to rise sometimes. But beyond that I don't quite understand them.
Apparently MIL wouldn't let her children wear clothes unless they'd been aired. As such DH had now taken to hiding stashing clothes in there in a plastic box when they come out of the dryer. I don't get it- can someone please explain them to me?
