Valentine is card effect when spectator freely selected a card and signed.
You then slowly drew two separated hearts on the back of the card which represent your heart and her heart or in the case of a couple, it would be her and her boy friend heart, but I know you will not perform in that situation ;)
Next, when the magic start to happen. You tossed the card in the air and as soon as you catch it, it magically linked together into a symbol of Love.
You could end the effect there with her big impression, but me, Nah... I would not stop there to be honest. So I have decided to add one kicker ending at the end when you drew a Cupid arrow, made it vanish and reappeared thru the linking heart. The card could immediately handed out to be examined and perfect souvenir.
Spectator loves it, Girl loves it, your girl friend will too.
Its that easy to do, easy to make and perform in minutes.
Welcome to Valentine.
