Our home is in the smallest castle category, so small space solutions are always on our mind.
These Under Shelf Baskets are something that have made it to our shopping list. Unlike the plastic-coated ones you see in hardware stores, they're made of silver-colored coated metal, and the fine mesh prevents smaller items from slipping out of the basket. Great for kitchen cabinets, as well as our single closet and its single shelf (!).
