Steve, mine may not be the best way, but I am trying to accomplish the same thing. Look in the last several pages of my thread and you'll see how I'm building removable covers for my side surrounds.
My columns were framed with 2x4. If I did it over again, I'd use ply instead. My end result is fine, but could have been better.
