Make outdated calendars last longer than a year by turning their artistic pages into envelopes

To make, cut apart the calendar at the binding. Trace an envelope template on each selected page, then cut out the traced template pattern. Placing the picture side out, fold on the dotted lines so three of the flaps meet. Glue the flap edges where they overlap. Once you have inserted your letter, use a sticker or glue to seal the envelope.
