My pantry drives me nuts, even when the door is closed! Th measurements are 12" wide for the shelves, but back wall to front wall 14.5". Width is 46" and it is 93" tall, but there is about 20" of space at the top that I suspect can't be used because of lack of clearance. Behind it is the fireplace and meet to it is an outside wall, so I can't think how to expand it. Approximately 50% of my canned/boxed goods are kept in the basement on wire shelving. I'm open to feedback and suggestions. Help!
