Who this list is for
A cardboard castle is a good rainy-afternoon build for school-age children who want a fort they can paint, decorate, and take apart later. Plan on one adult helper for box cutting and setup.
How to use this list
Start by gathering three to five large appliance cardboard boxes and six medium moving boxes. Put the drop cloth or old sheet under the work area. An adult uses the utility knife for doorways and windows; children use child-safe scissors for construction paper details. Join walls with packing tape, then use painter’s tape where you may want to reposition pieces.
Common mistakes
Do not make the castle too tall or block a room exit. Avoid putting a cut edge where children will lean or crawl. Skip permanent glue on the main boxes if you want to recycle the castle after the afternoon. Keep the recycling bag nearby for trimmings and spent tape.
What is on this list
The list includes large appliance boxes, moving boxes, packing tape, painter’s tape, washable paint, wide paintbrushes, washable markers, construction paper, glue sticks, paper plates, and aluminum foil. Paper plates and foil can become shields, signs, or pretend castle details. Cross off items you already own before gathering supplies.
When you are done
Let washable paint and glue dry before moving the castle. Separate reusable brushes, markers, scissors, and tape from cardboard scraps. Put clean cardboard in the recycling bag, then clear the drop cloth so the room is ready for normal use.
