It might be too early to predict, but I think this might be the most popular Christmas design for 2012–brought to us by Chad Ellenburg at Pleasant Valley Church in Winona, MN.
The red fabric represents the Gospel, the Scarlet cord stretched through eternity to save us in the winter of our our own souls – one 10 yard piece of crushed red silk.
The back wall is one piece of bleached muslin. They projected onto it from the front about 40 ft. away (just above the heads of the musicians).
The trees were made of rabbit-proof fence wiring from their local Menards (Home Depot or Lowes). They covered them with white sheets and painted the details. They used rebar tie-wire to suspend the trees and branches from their grid. Then they added in some real branches to sell it.
The painted the stage walls and roof black to make all the elements pop out.
