Look under any pantry shelf and you'll see it: a band of empty air where the shelf ends and the next one begins. That space is usually about as tall as a box of crackers, which is exactly the space snacks and wraps waste. You don't need a new cabinet to use it — you need something that hangs from the shelf you already have.
Clip storage onto the shelf below
An under-shelf basket slides onto the bottom of an existing shelf and catches the things that otherwise roll around loose: spice packets, granola bars, the zip bags, the foil. It uses the dead air, not the floor, so a short pantry suddenly has an extra row it wasn't using.
What belongs there
Put the flat, light, daily-reach stuff in it — wraps, snacks, tea, the odds and ends that fall over in a deep bin. Keep the heavy cans on the shelf above where they're stable. The basket pulls down and forward, so the back of the under-shelf row stays as easy as the front, which is the point of using that space at all.
Pair it with the shelf itself
If the shelf above is crowded, a shelf riser on top and a basket below it turn one gap into two usable levels. For tight shelf layouts, also see narrow pantry shelf organizers for tight spaces.
