Non-profit organizations such as STAGE RIGHT depend on the kindness of strangers (sound familiar)? Specifically, we cannot run a large show without backstage help (carpenters, set dressers, props, stage crew, lights, sound, costumes, kid wrangling, and more). Our help extends to the front of the house where we need ushers, concessions, and people willing to create and distribute flyers, rack cards, posters, articles, and playbills.
What specific skills do you need? There are only two requirements: the desire to help and to learn. If you don't know how to do something, take the initiative and find out how to do something.
