Decide where you want to place your washboard in your home. Kitchens, bathrooms and laundry rooms are generally good places for a washboard.
Take a close look at your washboard. If it contains vintage lettering or a vintage advertisement, you may not need to add much decoration. Try hanging a black and white photo from the top of the washboard using rough twine and a vintage clothespin.
If the washboard is more battered than you like, spray paint it in a color that will harmonize with your chosen room. Or rub the washboard with paint using a rag for an antique look.
Once the washboard is dry, leave as is or decorate with stencils, a short saying or proverb, or other designs.
Place finished washboard in room of your choice.
