Marcus Navarro from River of God in Tampa, FL brings us these three materials working together.
For their back wall, they drove around town picking up pallets (free). Taking them a part was a challenge. It took them approximately 16-17 pallets to complete this project. With seven 2×4’s ( $21 ) and box of nails and screws, they spent about $35.
Their speaker left and right were elevated on a pair of industrial heavy duty shipping crates. They created a frame for the front and used the pallet wood on the lower part about 30in high to match the rear wall and the top portion was window screen ( 36″ x 48″) 2 rolls, to create a rocky illusion. They used five 2x4s plus 2 rolls of silver screen that cost them a total of $25 for both.
The rear boxes with the dots was a wash, rinse, and reuse from a different project, so they didn’t pay anything for them. But if you want to get a pricing idea, they paid $40 for a pack of 200 1″ half Styrofoam balls and Marcus used a 4×8 insulation panel (about 5 bucks) and a frame box with 1×1 wood and wrapped it in pallet wood. All in all about $60 for both.
One week later and working as late till 4:30am, they created this set. With an original budget of $200, they came in at about $120-$140 for this project.
