The best thing I did for my theatre is have frames on wheels constructed out of wood a couple inches smaller than a king sized sheet. Mostly they are covered with black sheets staple gunned on and sometimes we paint a backdrop on muslin and staple gun them on and sometimes we put paneling on them for interior walls. They move easily (bricks are on the back brace where the wheels are for balast), can go on stage or in the house for some off stage areas...I love them.
