Daniel Reim from Freie Christengemeinde Bayreuth in Bayreuth, Bavaria, Germany brings us this colorful backdrop.
The piece measured 2.5 x 15 meters.
It was a cotton sheer muslin painted with diluted gouache to keep the fabric transparent.
They nailed the material to wood panels with a layer of absorbing fabric underneath to absorb superfluous paint. This allowed the use of a backlight without unwanted shadows.
The design was sketched with charcoal using a string grid to scale, then inked black with brushes on long bamboo sticks and then colored in.
A velcro band was attached onto the upper seam and its counterpart nailed to a ledge on the stage. The three other hems were tunneled, a separate cord run through each tunnel so the backdrop could be stretched out.
LED flood lights were used to light it from the front and the back.
