LIVING ROOM TOUR - Industrial Shelving by Meg Padgett from Revamp Homegoods
shelf (not including scary artwork, yikes!)
DIY wall-mounted shelving :: Uses twin tracks & sturdy brackets; shelf heights are adjustable. Brackets are screwed to 3/4" boards that were sanded & stained. As was said, it's all about meticulous planning *before* drilling any holes :-) but otherwise a fairly easy project with readily-available components.
