I've seen successful follower boards made with a wooden top bar attached
   to a piece of 1/2 or 3/4 inch solid styrofoam insulation board (not the
   white pellet type, the bees chew that too easily). A really strong
   colony might chew up this type of board, but maybe these boards were
   designed for extra spring coziness, and would be removed in summer.
