Yes, I’m one of THOSE frugal types. The ones who wash and reuse their zippered baggies!
For the longest time I used to throw the washed and dried baggies into a big bag and put them in a drawer. But that was unwieldy. I would have trouble opening and closing the drawer, I had to dig through the bag to find the size I wanted, and sometimes baggies would fall down behind the drawer itself. . . It was just a mess.
Then I had a brainstorm! I realized that if I kept the cardboard boxes that the baggies originally came in, I could refold the clean baggies, one by one.
