Costumes are minimal - just a hat or scarf or something to identify the character. It is possible for one person to read more than one part. Any action that takes place is done symbolically. For example, sleep may be suggested with the reader's head lowered, resting on his chest. The man walking from Jericho to Jerusalem may be presented by walking in place.
Characters think out loud.
Readers focus their attention on the audience, not on the other readers. This helps the audience focus on the text rather than the performers. Save the performance on audiotape for playback. The teller looks at the audience, makes eye contact, interacts with the audience, and tells the story in her own words. It is sometimes necessary for the leader to tell the story when the scripture is too long to read the entire story in detail.
