Have you ever tried an organizing trick or hack on Pinterest that actually changed your life?

Maybe you repurposed an old file organizer from college to keep your plastic bags in an easy-access spot so you no longer have to dig through boxes in a cabinet.

Or maybe you picked up a couple dollar-store shoe organizers for the trunk of your car, and now your family can easily spend a weekends at the beach without having to pack several giant bags.

Or you tried that old-school soda tab hack for your hangers, and literally doubled your closet space.
