Gus Peders from Friends Church in Willoughy Hills, Ohio brings us this manly design.
Gus wanted to capture some grit and manliness in his stage design. So he created these flats with some some block and some plywood (four sheets for about $30). He screwed the panels together, spray painted the lettering on, and screwed the panels directly to the wall.
He threw some par cans on them and there you go.
The only cost was the plywood since they already had the canisters, block, and paint.
