Zero cost meant working with what I hadn't thrown out or given to charity yet.
I had some metal over-the-door storage that I was able to screw into the wall...
I had an old wire shoe rack.
To make good use of it, I labeled gift bags and clear zipper bags that once held bedding and furniture covers.
To make the most of the wire shelving, I found boxes that fit in the shelves and covered them with more photography from Anne Geddes.
I also decorated bright yellow file folders with Anne Geddes photography. The file folders fit perfectly in the boxes.
Last but not least, I had some cute boxes that I could stack vertically.
