Stars twinkle in the sky when you slide your finger across the waves.
The twinkling effect is from a slide switch.
When you press at certain points, you connect LEDs to the battery.
The card is thin and and light,
and fits in a regular envelope!
To make this card, you will need:
- LED Circuit Stickers
- conductive ink or paint (like the Circuit Scribe pen)

2. Trace over the gray lines with your conductive ink pen or conductive paint.
3. Stick LED Circuit Stickers over the sticker images.
4. Fold along the dotted line to make your battery holder and slide switch.
