When my kids were younger, they loved to hand out Valentine's to their friends for Valentine's Day. They would search all over the Valentine's card shelf looking for the perfect cards to hand out to their friends. However, their current favorite characters weren't always available.
If you have a child that loves LEGOs as much as mine, you'll love these FREE printable LEGO Valentine's Day cards. Just print out the file in color on a sheet of cardstock (so its a little thicker than a normal piece of paper) and have your child fill them out.
If you really wanted to get fancy for extra special friends, you could buy little LEGO packs and attach them to the card (rather than candy).
