The prop master and his/her team are in charge of obtaining and keeping track of all hand-held properties – swords, suitcases, books, etc. What they cannot obtain, they will have to manufacture. Props can be misplaced backstage, never to reappear. Prop stations belong on both sides of the stage.
Have the prop team at all dress rehearsals to work out prop placement issues. If King Arthur is entering stage right but Excalibur is waiting stage left, key scenes in Camelot will be jeopardized. The master/mistress will make a list keyed to the script to be sure errors such as these don't happen. It is very important that props are not moved.
A student or adult with a knack for details has volunteered for this job. Her father is a professional carpenter, which won't hurt if she needs to construct some period items.
One of the biggest problems is actors who decide to play with the props - a common outburst is, "Don't play with the props!" from the Props Master.
