Little shelf brackets designed to hold bins from the Dollar Tree
The shelf material in the picture is foam core from the craft store, the cheapest kind I could find. It works great for lightweight items, but wood would be stronger if you need it.
The shelf should be roughly 10cm (Roughly 4 inches) wide, and as long as you like or as your materials will hold up.
