Corner rod for planning outfits/what to wear the next day. Super duper clever for those wasteful corner spaces! You could put a corner shelf above and plan your shoes and jewelry too! --or just devote a space for such in future walk-in closet!
suitcase halves as shelves! i have not seen them used this way before (usually the suitcases are cut in half horizontally while closed--these are halved by removing the hinges, which keeps the structure intact).
