Tired of organizing the same space over and over again? Time to find a new system that works better for you! Re: refrigerators & pantries: Designate one shelf in your refrigerator for leftovers. Assign a place for everything. Pantries: rotate as you go. New items always in the back so that older products are used first and are in front. Again, assign a place for everything, so there’s no rummaging or searching.
