This helmet idea can easily be adapted for many different costumes. This helmet should fit children under 6 years old. If you want an older child to wear it, you may have to cut and join two milk cartons together.
Parental supervision is recommended.
How To Make It Hold the milk carton upside down by the handle. Look at the photograph as a guide, and cut all the area where the handle resides and the milk carton top off with the scissors. Our particular milk carton actually had a difference in texture on the carton where we cut and that gave us the basic shape of the helmet. Trim off any sharp points. Paint the helmet on the outside and then let dry.
