"Soup can, cookie sheet, magents & hot glue gun" Great idea for the kids' room so they can find their art supplies better and easier. Could have this in the kids' room or in a central location in the house.
Buy a Bucket Boss (a portable tool belt that hooks on a bucket) and add the kids' art supplies & small games. Inside holds big stuff like paper and all the pockets on the outside are for pens, markers, glue, and scissors.
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.
