Sheet metal inside cupboard to hide all the crap otherwise on your fridge ~ also do inside some of the doors with cork or chalkboard paint. keep the clutter hidden! If I go with shelves instead of upper cabinets, use this on inside of pantry doors.
Great Idea - "Crap Baskets" during the day as you find things, place them in the basket. When the kids are on their way upstairs, they take their "crap basket" up to their rooms to be put away. But store basket in 'out of sight' place
