A good idea for a small bathroom, under hanging shelves for things like cotton balls, cotton swabs, etc. Also great in the kitchen, for a spice rack over the stove. Just hang jars from bottom of the cabinet.
Upcycle plastic containers (spray / detergent bottles) into baskets, gift bags, containers, etc. Maybe larger square gallon jugs for holding craft supplies or keeping small things together in the closet, or.
