Fold your main piece of cardstock into a card shape and lightly trace a dotted border around the edges using a pink pen for a stitched look.
Cut four small rectangles from scrap cardstock to act as mini playing cards. Rounded corners make them look more realistic.
Draw a spade, diamond, and club on three of the mini cards using markers, keeping the symbols bold and simple.
Punch or cut a small heart out of the fourth mini card so it matches the phrase.
Attach all four mini cards to the main card with foam tape so they stand out with a nice 3D effect.
Write “you stole my heart” by hand, placing the words above and below the suit symbols.
