Tug at your valentine's heartstrings with an embellished envelope. Cut out the hearts from colored card stock using a specialty hole punch (available at crafts stores). Poke two holes into each heart with a needle, then sew the hearts onto dual-capacity envelopes (buy your own or download our template) using the needle and silk beading cord. Secure stitches with a double knot on the backside of the flaps. After inserting the valentine, close the envelope by winding a 5-inch length of the cord in a figure-eight motion around the hearts.
