Lasercut Stretchy Conductive Fabric Traces

Step 4 Snaps as connectors for non-washable components.

LEDs, piezo transducers, small buttons and the like are generally washable. Some more expensive components however you might not want to just stick in the washing machine. In the dress I used a bluetooth module and some speaker drivers I decided I wanted to remove when washing, so I used snaps to make the connections.

Sew the snaps onto the ends of the traces with conductive thread, making it plenty tight. For good measure you can make sure it doesn't fray with a dab of thread end glue. Solder the other end of the snaps onto the end of your signal wires. To make sure that I don't get ground and signal wires mixed up, I used differently sized snaps for the two.
