Duke Dejong (who is secretly one of my heroes) designed this stage for First Assembly of God in Cedar Rapids, Iowa using loads and loads of poly stretch and spandex to make 3 and 4 point shapes. All of the shapes were cut by hand in house. (You can buy those fabrics at Dazian or Rose Brand.)
To hang them, each point was tied into a knot around their anchor points on the truss. Each truss and shape was up lit using LED fixtures. To add a bit of variety, Duke sometimes would project gobo patterns on the fabric as well (not pictured).
PS Folks. Duke is now going solo doing consulting for churches. If you’re looking for stage design help, hit him up. He just might make your wildest dreams come true.
