Materials and Tools
Here is a list of all the materials and tools you'd need to follow along:
- Copper Tape - 5mm width (~18" of tape per card)
- LED *see note below about LED choices
- Coin Cell Battery - 12mm (CR1225)
- LilyPad Button Board -or- LilyPad Slide Switch
- Cardstock (2-3 pieces)
- Vellum or Parchment Paper (optional) - creates a nice diffused effect for LEDs in the center of the heart in the I <3 U design
- Clear Tape
- Gluestick/Glue
- Scissors/Hobby Knife
- Decorating Supplies - stickers, markers, or paints to embellish your designs
*A note on LEDs:
We recommend using the smallest LED you can find - 3mm work well because they don't add too much bulk to your card when folded. For extra flair, try using cycling RGB LEDs. We've also found that cutting individual LEDs from a set of LED String Lights works well - you will have to use a hobby knife to scrape the coating off of the wires before using. We'll cover that process later in the tutorial. Feel free to experiment with different LEDs to find what works best for your project.
