Introduction: 20mm Small Space Shoes Shelf (Fold Able)
There is a tiny space between the wall and the door.
The space is about 20mm, I make a PVC structure (20mm PVC tubing) for hanging "wet" shoes and simple storage. (such as umbrella and slipper)
I make the whole rectangle structure that insert into this small area, so this PVC shelf is not fixed by any screw.
