|Next cut out the large curly ribbon piece which fits underneath the cantilever over the stage. Scoring the mountain and valley folds carefully.
Note the curved supports underneath the roof. Use a round pencil or wire to curl the piece to match the curves of these supports under the roof exactly (fig. 5). Roll the long ends of the ribbons upwards so that they will curl up above the roof of the cantilever. Once the ribbons are shaped correctly, glue the piece in place with the back end fit in place above the top of the stage.
