First of all, only 1 follower board should be used. Standard
          1" lumber is fine. Use 1x4, 1x6, 1x8 or 1x10 depending on
          super size. Cut each board 18 and1/2" long and place a
          finishing nail in each end at about 1/2 inch down from the
          top. These boards replace a frame at one side of the brood
          nest. These boards are easy to remove so that your 9 frames
          can be worked easily. Go through the frames from one side
          then place the follower board on the other side when
          finished.  Follower boards are not critical as to dimension
          as long as bees are worked frequently. It they are left in
          for many weeks without working your bees you may find brace
          comb built onto the side of your board. You can cut ears
          into a longer board to make it fit if you wish to be a
          little more fancy. Follower boards are simply a matter of
          preference. I have used them for many years and like them.
          At this time, I am not using them. They are inexpensive and
          easy to make. I recommend that you try them on 1 hive and
          see if you like the idea.
