There are tons of gadgets and tricks to help us eke out more space in our cabinets. Some are better than others (read: The Supposedly Brilliant Kitchen Hack I Didn't Love and Immediately Undid). But when they're good, they're really good.
Take this over-the-cabinet-door rack, for example.
Crafted out of sturdy stainless steel, the rack requires virtually no installation (just hang it from the back of the door and you're done), and it converts unused space into storage space.
It can hold a variety of cutting boards and sheet trays (getting them out of the oven or precarious stacks that are impossible to navigate), and even things like plastic wrap, aluminum foil, and parchment paper, maximizing your space and keeping often-used items within arm's reach.
