Wall brackets from hobby lobby and wood plank (see "home/decor") and 4 of the organization boards (calendar, full white board, full cork board, and mail sorter). Instead of books on shelf, add burlap and lace boxes (see other pin). Add filing trunk to opposite wall and mount shelves for printer. Or add filing cabinets and printer on top.
What it is: An entire wall dedicated to storage and brainstorming. How to do it: Buy enough simple veneer cabinets to line your wall; paint them to match your decor for a custom credenza look. To get enough pin-up space, wrap a piece of Homasote board (made of recycled material and often carried at home centers or lumberyards) with burlap. Wait for a framing sale to frame the board, or hang it as is.
