When I was a child and a poor one at that this is how our laundry was washed.  Today with all the modern conveniences like a washing machine and dryer I kept thinking what would happen if we had not power.  I have become a prepper and make my own laundry soap and bought this board just in case.  Boy did it bring back old memories.  It now hangs on the wall just waiting to be used in an emergency in my laundry room.  By the way we had to use these in boot camp.  It is better to have it and not need it that to need it and not have it.
