How to Build a Warmer Box for Food
- 1). Find a cardboard box that is large enough for your covered food container plus several inches all around. Remove the top flaps. If necessary, use the box cutter to cut a box to size.
- 2). Layer the bottom of the box with about an inch of newspaper.
- 3). Set the food container on top of the newspaper, centered in the box.
- 4). Use more newspaper to fill in between the sides of the box and the food container, and layer about an inch on top.
- 5). Fold a bath towel to the size of the box and tuck in tightly over the top of the last layer of newspaper.
