I personally had fun with this because I learned how to sew!

I decided to make a simple button based on the example our instructor showed us in class. She used foam, velostat, alligator wires, an LED, and a 9V battery.

I thought about doing something similar with the conductive thread. But since I was a first-time sewer, I didn’t have time to figure out how to work the conductive thread. Instead, I went for a simple 3V coin battery and LED circuit combination.

I made a circuit sandwich with two pieces of foam and stitched fabric. I put the button inside and essentially sewed up a light-up pillow.
