Construct your LEGO heart so you know how wide to cut your gift tags.

As you can see from the above image, you have a single LEGO piece left over. You will need this to form the bottom of your heart.

Cut your card stock using the heart size as a guide. I turned the heart upside down and cut the cards into the width of the pink LEGO baseplate.

Hole punch the top of your card, so then you will know to stamp underneath that.

Put paint on your LEGO heart and press it onto each card. I swirled the paint a little on a paper plate so that I had a variety of pink and red on each card.

Once you have stamped the heart on your card, dip the single LEGO piece into the paint and add a dot at the bottom of your heart to give it more shape.

Set your cards aside to dry. Once they are completely dry, tie string or ribbon through the hole.

I made cards that open up so you can write a message inside, but to save on card stock, you can cut this into two pieces and write on the back of each heart instead.
