Charlotte's Web   We had Charlotte enter the stage lowered, as a spider descends. The audience loved this move.   Mike Brooks, St. John Theatre, Laplace, La.   We built a large barn set and did the fair scenes downstage with only a stall and some hay bales. In the barn, we built a loft for Charlotte that allowed us to create a large yarn web.   Tom Kirk, Hart Middle School, Hart, Mich.   Use a simple set. I kept the chorus in full view of audience all the time dressed in Pierrot costume so they were apart from the cast. Animals dressed as humans with animal masks.   Bill Bennett, Peachland Players, Westbank, British Columbia, Canada   Get costumes done early! We had problems with our spider costumes!   Amber Peters, Seneca Valley Senior High School, Harmony, Pa.
