Tools & Prep

Test that each LED works by pinning it onto one of the included coincell batteries. It will only light up one way so if it doesn't at first, try flipping it around.

The candle flicker LEDs have a chip inside that causes the light to twinkle.
Notice the longer lead is on the positive side marked +

The LEDs pictured are wired in parallel with the 3V coincell. We recommend powering two LEDs with one battery, which is great for projects in pairs like shoes.
Read our conductive thread guide to get to know this quirky steel textile.
Pliers help you shape the leads of the LEDs.

Heat shrink tubing insulates your circuit to prevent shorts.
Sharp scissors are a must!
