It's hard to resist Valentine's Day suitors when they come bearing sweet treats.

Use the tack to poke arm and leg holes in the card. Position one set of holes an inch from the top and the other half an inch from the bottom.
For the arms, fit the ends of one pipe cleaner through the upper holes from the back of the card. Fit the other pipe cleaner through the lower holes to create legs. Bend the ends of the legs to shape feet.
For a head, cut a heart shape out of construction paper. Glue on googly eyes and draw on a nose and mouth. Then, glue the head to the front of the card.
Finally, wrap one arm around the lollipop stick. If you want to include a Valentine's message, write one on another paper heart and fit it on the tip of the valentine's free hand.
