The Shoe Bag Solution. Short on closet space? Use plastic or cloth shoe bags hung on the back of your bedroom or closet door. Hanging shoe bags need 38 to 60 vertical inches of hanging space. I find wire ones to damage line of shoe, especially sandas.
Linen Closet: Roll with It. Save space in a shallow linen closet by rolling up towels instead of folding them. Put lost space to use by installing towel racks on the back of the door to hang wrinkle-susceptible linens, such as tablecloths.
