Why have somebody put words in your mouth when you can just do it yourself? That’s the concept behind the Chalkboard Door Hanger. It’s a double-sided chalkboard that can slip over your doorknob and allows you to colour your words exactly as you deem appropriate. Some statements simply work better than “do not disturb”. Comes with some chalk and an eraser.
