I am in the planning stages of what will become a closet organizer for a large walk in closet. In one area of the closet I am looking to install an 8 foot long 20 inch deep shelf. Under the shelf, but not attached to it, I will run a rod for hangers. I think that I will use for the shelf a 3/4 inch 20x96 stain grade ponderosa pine panel from lowes. See the product here: http://www.lowes.com/pd_72884-99999-...boards$y=0$x=0
A friend of mine says that I should not use this product because it lacks stiffness and will sag too easily. He recommends using a sanding plywood. What do you think? I was planning to brace the shelf on three of the four sides using 1x3 pine. I was also planning to attach the shelf to the bracing with glue and screws. Should I also brace the pine on the front side of the shelf? Should I avoid the lowes panel and use plywood? In what other ways should I brace the shelf? I was thinking of two triangular wood braces creating three separate equidistant sections or, maybe full pine boards 20 inches deep running the full length to the floor - through which the rod could run. I'd appreciate any feedback you could provide.
