We have an old home. The doors have 4 panels in them. I painted the door panels with chalkboard paint carried at home improvement stores. I then painted the name of each grandchild on a panel. The older children got the higher panels with younger children getting lower panels. I keep chalk in the house and use wet paper towels for cleaning. Even teenagers put something on their panel. A great extra; I frequently get loving messages; even from friends' visiting children.
