Bob from New Seasons Worship Center in East Freetown, MA brings us this design using vertical blind slats.
Bob built 2×4 wall panels with 1/2 OSB sheathing and put 1×3’s on it spaced 4.5″ apart. He built 4 like that running them horizontally. Then he built the center two panels the same but put the 1×3’s at a 45 degree angle so that when he put the two panels together it formed a V. He also painted them white so double sided tape would stick.
Then he applied PVC vertical blind slats, putting the inner one curved out and the one on the 1×3′ curved in. He only taped the top edge with double sided carpet tape.
He also build two light towers to cover poles on their stage.
