Russell Martin from Williams Memorial United Methodist Church from Texarkana, Texas brings us the first one. He used some window frames made for an earlier stage design, covered them with wax paper, and put christmas lights behind them.
The second comes to use from Tyler Rippel at First United Methodist Church in New Philadelphia, Ohio. They cut their window frames from one 8′ sheets of plywood. Then they added the crossbars, stapled natural muslin, and stapled some Christmas lights behind the fabric.
