This will be good to have pinned later for that time of "there's too many shoes but I can't afford decent shelving yet" --- Shoe explosion? Round up some old tension rods, set them up in your closet, and voilà, instant customized shoe rack!
Tried this and it is amazing, freed up so much pantry space! No more toddler snacks floating around all over the place. This isn't my pantry but illustrates the idea! (Over the door shoe rack used for pantry organizing.)
