I like this idea for my produce in my garage! Laundry bags can be made into storage for potatoes, onions and garlic. It can store a large supply of produce and ventilates well. Lots more ideas at JewelPie.
Use the sides of your closet to hang up more rods. Side of closet often have that weird "dead space" Add tension bars and hang additional clothing up, a scarf rack or hang purses so they don't get smashed in storage.
