These thematically related collections offer a number of features which have made them very popular. Casting is extremely flexible, often allowing for performance by from one to more than a dozen actors. Set requirements are also very flexible, ranging from a single unit set modified to accommodate all pieces to more elaborate design options. Perhaps most important, the pieces which comprise each full-length play stand alone as shorts and monologues, allowing tailoring to suit in relation to length of performance and particular interests. Many have been used individually in short plays festivals, evenings of monologues, and forensic competitions throughout the United States and internationally.
