To start, buy a blank card or make one of your own.We cut a piece of light pink cardstock to 7 x 10 inches and folded it in half. Then we added an insert of printer paper that was 6-1/2 by 9-1/2 inches (1/2 inch smaller than the card).
Print one of our free heart outlines on coloured cardstock and cut out the shape.You can also print on regular paper and then trace the heart onto cardstock.
Add glue tape to the back of the heart (the side with the black outline).
Place the cardstock heart on the front center of the card
Step 3: Glue buttons to the card
Choose a button to add to the card and add tacky glue to the back of it.
Place the button onto the card.We placed this button a bit away from the edge, knowing we had smaller buttons to fill in the space. You may want to plan which buttons you're using before gluing them into place.
Add a second button onto the card. Small buttons work well near the "V" dip of the heart.
Continue placing buttons as close together as possible.It's okay if there's a bit of a gap between buttons, or if they go over the edge of the heart a bit.
Continue adding buttons with tacky glue until the heart is full.
Allow the glue to dry. This can take several hours.
Step 4: Write inside the card
Write your Valentine's Day message inside the card.You can write a basic greeting, like we did here, or add something like "My heart is yours, Valentine!".
