This project is based off my LED cuff bracelet Instructables, this time using a circuit sticker.
3V coin cell battery
sewable battery holder
non-conductive thread or embroidery floss
Place the circuit sticker on the felt. Make sure the negative end (-) points to the negative end of the battery holder (slot). Sew down the snap to the positive (+) end of the circuit sticker and break thread.
Sew the negative end of the circuit sticker to the negative end of the battery holder and break thread.
Sew the positive end of the battery holder to the snap.
Insert battery and connect the ends of the bracelet together. It should light up!
Decorate using non-conductive thread.
