If you have many classes, you can do more. Let children choose what they want to be. Send very clear directions to parents at least three weeks ahead of time. All decorations can be made in school. Headbands, bracelets, necklaces, hats, and belts are easy to make.
Older children can design their own.
All these art projects are interesting and educational. Parents can help with the costumes. Some children may want to wear their own national costume. Other children can put together a costume with the help of parents and grandparents. Many families will have something original to add to the costume.
