After hand-sewing the panel on the front of the dress, I attached the mic with normal black thread to keep it in place. Sewing the circuit between the Gemma board and mic was a little tricky. I used a fabric pencil to sketch in the traces on the garment, which helped me keep track of the traces between layers of fabric, back and front.
I really liked how the dress turned out! The stripe down the front was a perfect accent for the LEDs. PLUS my workshop had a winning bid!
My son helped me demonstrate the sound reactive mic with the LEDs!
