L.E.
Seven years ago, I transformed the lower half of the wall in my laundry/mudroom into a magnetic chalkboard. I used two coats each of magnetic and chalkboard paint. My three granddaughters have tested its durability with chalk, magnetic numbers and letters. The wall has even withstood their enthusiastic attempts to wash their wall with soap and water
To date, I rank the wall as one of my best investments in my grandchildren. The chalk dust disappears with a quick "once over" with a damp mop--a cheap price to pay for hours of creative activity away from television!
