Joseph dutifully assembled all the hearts.
I *might* have helped attach the keychains.
Joe Joe and I also teamed up to create a giant heart out of Lego bricks to use as a photo prop since I wanted to include a picture on the back of the card.
Then I got to work with printing and cutting....
and even personalizing a few cards for teachers.
I may be biased in thinking they were cute enough as is, but punching a hole and attaching the keychains just took them to a ridiculously cuter level.
The completed card, front and back.
I sealed the cards in cellophane treat bags so the kids could see both sides as well as their special present, and labeled them with each child's name in the Lego font.
Joseph might have been this happy had his Valentine party not been canceled to due yesterday's snow day. They'll do it sometime next week, and now we have more time to decorate a mailbox for him in which to collect all of his friends' cards.
UPDATE, January 2016: Wow, I can't believe how much interest there has been in this post since our crafty little valentine was featured in a round up on POPSUGAR Moms about Lego valentines! Thousands of page views, and lots of questions about how to make them!
I made a cardboard template with the measurements in the picture below, and used an Exact-o knife and ruler to cut out the shaded areas.
The Lego piece is called a 2x2 coupling plate, design # 3176. I picked up the keychains at a local craft store. Another great option is to use ribbon to make necklaces.
Happy crafting, and Happy Valentine's Day!!!
