Step 9Plug and cable
Trace the cable stencil twice onto the piece of non-stretch fabric. Cut out small squares of stretch conductive fabric and fuse them to the positions of the Xs marked on the cable stencil.
Prepare your sewing machine with conductive thread. Wind the 117/17 2ply conductive thread onto a bobbin. For the top thread of the sewing machine you can use any colour you like. Preferably make the GND cable stand out by choosing a different colour than the rest.
Sew from the patches of conductive fabric all along the meter of non-stretch fabric to the other end (see photos and stencil), leaving about 10-15 cm extra of the conductive thread that later need to be sewn to the perfboard.
Make sure that the threads do not fray or make any sort of contact between one another. Their spacing should be about 2mm so that they line up with the spacing of the holes on the perfboard.
When all the threads have been sewn, pierce female poppers through the patches of conductive fabric. So that the face of the popper is NOT on the side of the conductive thread.
If the fabric you used is rather thin, you can reinforce it in the head part with an extra layer and some fusible interfacing. This will stop the poppers from tearing the fabric when you connect and remove the plug.
You can also add some fusible interfacing on top of the conductive side of the threads, so that when you have sewn and turned the cable inside out you can fuse this fusible by ironing over it and it will stop the threads from making bad contacts within the cable.
Lay right sides together (conductive stitches facing outwards) and sew the pieces for the plug and cable together, leaving the end with the loose conductive threads open. Turn the cable inside out. And close by hand.
Stitch the loose conductive threads to the perfboard. Make sure none of them touch each other. You can use some of the fabric glue to isolate them when all of them have been sewn.
