Note: As you can see, the LilyPad LEDs and Lilypad Button were sewn into the fabric, but you can easily switch these for normal, through-hole LEDs, and a button soldered on a protoboard with the other soldered components.
Warning! Make sure to solder hook-up wire to your heating pad connections. DO NOT try to use conductive thread to connect the two heating pads.
