17. Use old Christmas cards and boxes as decorative dividers
If you're one of those at the end of the year with a big pile of Christmas cards, you may want to update them for better use. You can line up and put together with tape or glue cards into cardboards. There is also the option to cut an old Amazon box and use cardboard in the same manner.
It is possible to purchase boxes that already have splitters if you want to save yourself from the hassle. Nevertheless, you can build an infinite number of boxes on any budget, if you do it yourself. And you'll feel better about yourself realizing that instead of tossing the cardboard into the garbage, you've reused it.
