Start by placing your kraft envelope on the front of the card to find the right position, usually centered and slightly lower than the middle.
Cut or punch several small hearts from red, pink, and white cardstock. Mixing the shades creates a more playful and full look.
Open the envelope flap slightly and glue some hearts inside so they look like they’re spilling out. Let a few stick out at angles for a natural effect.
Add more hearts floating above the envelope, arranging them in a soft upward scatter.
Tie a bow with the red string and glue it to the bottom corner of the envelope for a sweet finishing touch.
Attach your Valentine’s message at the bottom of the card, keeping it simple so the envelope stays the main focus.
