Since it’s often the busiest room in the house, the kitchen is an ideal place to leave messages. But rather than plastering the walls with sticky notes, consider painting the inside of a cabinet door with chalkboard paint to turn it into a permanent, erasable message center. Start by masking off the area on the inside of the door with painter’s tape, then apply the chalkboard paint with a brush. Allow the paint to dry for 24 hours before applying a second coat. After drying for 24 more hours, the chalkboard is ready for use with regular chalk.
