Emily K -- I'm too late to this thread, but was going to ask if you have a lot of dresses to store? The rod space in my closet is all double-hung (above and below) and that leaves me very short on space to hang longer items such as dresses.
I don't have a ton of dresses -- perhaps because closet considerations influence my purchases.
I admire your patience with shoe storage! Like Janet, if I had your wrapped-in-boxes system, within a week I would find myself with a stack of empty boxes and shoes all over the floor.
