Sure, you could pay a visit to Hallmark and pick up an overpriced card with a pre-printed message. Or you could flex your creative muscles and design a handmade card that is sentimental and therefore likely won't end up in the garbage on February 15.

This particular design is made unique by glowing red LED lights (pink would work as well) and a personalized message. Use some recycled cardboard and voila, a valentine that is sure to score you some romantic points, or maybe just help you score period.

Intro - Opposites Attract: A Magnetic LED Valentine Heart
This Instructable will take you through the steps on making a magnetic LED valentine by which one can convey their feelings through a thought-felt message and glowing red LEDs. ;) Send your loved one one half, get a puzzled look, and the unite the two to form the one Valentine to RULE THEM ALL!

Step 1 - Gather Materials And Cut Out Your Heart (from cardboard)

Start out first by cutting out your two heart halves from the cardboard or other material you obtained. I just cut once by duct taping the two halves together and sketching a heart on one side.
