Put romance into writing with this Valentine's mailbox made from a half-gallon carton.
We created the ship's paper waves by using a large, round paper punch to cut half circles from strips of card stock.

Start with a clean carton. Cut off the plastic spout or tape the cardboard spout shut.
For the bow, cut a 3¾- by 10-inch strip from a cereal box, fold it in half, and tape it in place as shown.
Use tape and a glue stick to cover the carton with paper. (For a smooth look, we taped paper over the top and bottom of the ship before covering the sides.) Cut a mail slot in the ship's top.
Use a glue stick to add circles, hearts, and stripes to the sides.
For smokestacks, roll three 2½- by 5-inch pieces of black paper into cylinders and apply glue to the overlap. Add thin paper stripes. Glue the stacks to the deck.
