So you hang one in a cabinet and dump all your dirty reusable napkins in it as they get used. When full, you throw it in the laundry and it requires no sorting and very little effort to process back to clean. Then you get one for cloth snack bags. Then for rags.... you see where I'm going with this? This one purchase (the mesh bag) opens the gateway to so many other switches to non-disposable/buy it for life type things.
