Basement bathroom door for cleaning supplies. Kitchen to basement door for pantry items. Back of girls' door for barbies. Inside girls' closet for shoes. Inside my closet door for belts and scarves. Entry door for shoes, mittens, etc.
Kitchen storage idea - Dividers in the deep space above the oven or refrigerator are an efficient way to storage your platters, cookie sheets, cutting boards, bakeware, etc. Add shelves above the dividers to maximize storage in taller cabinets.
