Hi ! You can collect or buy pine cones , the an adult can hot glue a loop of ribbon to the top , then the kids can brush on some glue and glitter on them . You can have them paint popsicle sticks white ( can add glitter white paint is still wet ) then glue them on top of each other to make a show flame shape ! Cut strips of construction paper or wrapping paper and tape to make chains !
