Storage is one of the more obvious ways to reuse cardboard. After all, who doesn't have a box of old invoices, pay stubs and bank statements lying around the house? Cardboard offers many more inspired and useful storage opportunities for seasonal, day-to-day and other purposes.
For example, holiday lights can be twisted around cardboard wrapping paper tubes to prevent annoying tangles. Electrical cords, yarn, string and pretty much anything else that may get tangled up can be stored this way, too. Empty liquor boxes with dividers offer a safe place to nestle delicate ornaments, crystal, light bulbs or other breakables. Handymen may use those same liquor boxes to conveniently separate household hardware, including nuts, bolts, nails and dowels.
And if you thought the only thing a paper towel tube was good for was a makeshift megaphone, think again. These cardboard tubes are ideal for keeping important documents like marriage licenses, bills or children's artwork wrinkle-free.
