A small band of Twin Cities playwrights takes matters into its own hands through the Workhaus Collective — developing, critiquing and producing each other’s works. The next offering comes from Jeannine Coulombe, whose Planting Shelly Anne hits the stage this weekend at the Playwrights’ Center. Step into the creative process and a rehearsal through this 3-Minute Egg. Performances continue through February 14.
