1x4 x 8 foot furring boards costs about $1.50 each. Bought about 50 of them and made sure each was not warped.
I’ve known Chris since his dad brought him to shows when he was about 9 or 10. He is a service manager at a dealership, good guy!
This is part of my collection which is 2 separate units, 10 shelves each which I stained the boards.
