Step 3Iron on Circuits
Sew in your foam buttons into the bra cups.
Next we need to cut out strips of conductive fabric and double sided interfacing to make the circuits go around the back of the bra. I thought using the fabric was much faster than sewing but you are welcome to use conductive thread instead of fabric. Some parts I did sew because the area was too tight. I highly RECOMMEND gluing all knots of the thread with a small dab of hot glue. Conductive thread tends to fray and unwind. Gluing it ensures that it does not touch others and short circuit.
I highly recommend pinning the interfacing and the fabric to the bra before ironing. It's tragic when you lift the iron and your fabric got all twisted or bent :( None of the circuit paths should touch or overlap one another.
Make sure that a piece of the conductive fabric is connected to the buttons in the cups.
Wrap and iron on the conductive fabric all around to the center of the bra back. Leave a little extra for testing.
It looks sort of cool and sort of a mess - but all of this will be covered up in the end.
Now test! Make sure your buttons work.
