Here's another great idea to make food toys from recycled materials. Wash and cut open a milk carton. You can use it to make tiny milk or juice cartons about 3 inches tall to go in your toy refrigerator. You don't need to write in Japanese like my wife did. The sizes I give are the original measurements in cm. You can adjust them to more manageable measurements as you like.

Cut a rectangle from the milk carton 11 cm(4.3 inches) by 7 cm(2.8 inches).
Fold the rectangle every 1 inch down the length to make 4 segments. It's important to leave about a quarter of an inch flap at one end. This is where you'll glue it together.
Fold the carton into a 2.8 tall rectangular box and glue into place with the flap. The printed side should be on the inside of the box.
Push the sides and pinch the top 1 inch of the of the box into the carton top. Glue and/or tape in place to secure.
Cut a 11 cm(4.3 inch) by 4 cm(1.6 inch) rectangle from origami paper for the label.
Glue the paper onto the carton.
Add details like a cow or fruit and write the words "milk" or "juice".
