Fold a piece of white cardstock in half to form the base of your card.
Draw and cut out several heart shapes from red and pink construction paper.
Fold each heart shape in half vertically to create a center crease.
Take three folded hearts and glue one half of each to the next to form a 3D heart.
Apply glue to the outer halves of the 3D heart and press it into the center fold of the card.
Ensure the heart pops up when the card is opened and folds flat when closed.
Use markers or pens to decorate the front of the card with drawings or messages.
Add additional paper cutouts or stickers to enhance the design if desired.
Write a heartfelt message inside the card using colorful pens or markers.
Double-check that all glued parts are secure and aligned properly.
Allow the glue to dry completely before closing the card to avoid sticking.
Trim any excess paper that may extend beyond the card edges.
Use a ruler to press down folds for a crisp and clean finish.
Add glitter or embellishments carefully if you want extra sparkle.
Test the pop-up mechanism by slowly opening and closing the card.
Store the card flat under a book for a few minutes to help it set.
Clean up any glue residue or pencil marks for a polished look.
Place the card in an envelope or gift it directly to your Valentine.
