The lumber is reclaimed yellow antique pine that is over 100 years old. It came from M. Fine Lumber Company. The ashen surface of the pine was planed, belt sanded, routed and then stained and finally sealed with a light coat of polyurethane. The support brackets are drilled into the wall studs and able to support 1000 lbs each. They came from www.supportbrackets.com. The shelving supports my ethos (no pun intended) to keep things real and simple. More pictures and the full explanation can be found here.
