How to put it together
- 1
Cut your cardboard or foam board into a neat rectangle, roughly 36 inches tall by 18 inches wide, ensuring it fits your frame comfortably.
- 2
Paint the front of the board with your base color (brown for wood, or a bright color like pink) and let it dry completely.
- 3
Use a darker shade of paint or a marker to draw rectangular panel lines to give the door a classic molded look.
- 4
Glue the dummy doorknob to the right side of the door, about halfway down, using strong hot glue or duct tape on the back.
- 5
Apply stick-on house numbers near the top of the door and draw or attach a faux mail slot below the doorknob.
- 6
Measure and attach two loops of nylon webbing or ribbon to the back of the board using heavy-duty duct tape, creating shoulder straps.
- 7
Slip your arms through the straps to wear the door panel on your chest, and pair it with simple, dark clothing underneath.
Makeup & hair
Keep makeup and hair neutral so they do not distract from the door panel, or wear a simple black beanie to blend into the background.

Tips
- Keep the cardboard lightweight so it is easy to stand and walk around in for hours.
- Ensure the shoulder straps are taped very securely to the back of the board so they do not snap mid-party.
- Wear comfortable, plain dark clothing underneath the panel to make the door stand out visually.
- Leave your hands free by avoiding holding any hand-held props, as navigating doorways while wearing a door can be tricky.
