What you need:
1 card (3 color papers, 1 small paper)
2 copper tape strips
1 paper battery holder
Step 1: Choose a Design
We used the "Cricut Design Space" to find a valentine's card design that we liked. Follow the directions using the Cricut machine. If you do not have a Cricut you can just cut out the design using scissors and/or an Exacto knife.
Step 2: Create a Circut
Based on this tutorial:
Step 3: Make Sure LED Works
Stick the LED on the battery. The long leg of the LED is the “+” and the short leg is the “-.” If the LED does not illuminate, flip it over first to make sure you did not have the sides mixed up.

Step 4: Tape the LED to the Copper Tape.
Tape the LED to the Copper Tape.
Step 5: Put the Battery Into the Battery Holder
Make sure the positive side is up. If that doesn't work, flip it over. If that doesn't work, the battery is dead or there is not a connection being made with the LED.
Step 6: Finish Your Card
Glue everything together so that the circuit is hidden behind the top layer of construction paper.
