[QUOTE=oksewglad;6447819]Instead of stapling the outer fabric to the board, just staple the padding but make a "pillowcase" for it and when it gets dirty either easily wash or replace.
This is what I did. It makes it so much easier to be able to slide off the dirty, starchy "pillowcase" and throw it in the washer. I can't imagine how to clean it otherwise, except to have to unstaple it so often.
