Sand the wood plank to remove rough areas and edges. Wipe away the sanding dust.
Apply craft paint to the wood plank (both sides). Also paint the wood beads. Use enough coats to fully cover and let dry.
Apply the clear chalkboard paint over the top of the paint, using 2 - 3 coats (follow bottle instructions). Let dry.
Measure and cut scrapbook paper to fit the top of the hanger. Apply Mod Podge to the hanger, smooth down the paper and let dry. Apply a top coat of Mod Podge and let dry.
Drill two holes into the top of your planks (you can use painter's tape to avoid splintering).
String the twine through both holes and tie at the top, stringing on a bead between knots. Hang.
