The Spring Bag

It is an interactive bag design. And here is the material list:

green silk,

snap button,

copper thread,

LED (green, white, yellow)

wood,

zipper,

fabric glue

Use the laser cut machine to cut two wood sheets into pieces.

I used fabric glue to make it stable, you can use double sides adhesive tape instead.

Make sure that you stretch the fabric before you sew them together.

The holes on wood sheets are cutted for snap button and straps.

On one side of the bag, build the circuit as the picture shows. Make sure that you put the LED on the edge of the wood pieces. I used conductive fabric tape to finish the circuit.

This part is a little complicated. You need to build the circuit next to the zipper. On one side of the bag, it is a parallel circuit with 3 white LEDs. On another side, sew 2 yellow LEDs and make the circuit as it shows. So that when you zip up and zip down, you can turn on and turn off different LEDs.

You may want to test the circuit and make sure it works before you sew the two pieces of the bag together.
