Step 4: Sew your stitches
Take the conductive thread single and stitch into the neoprene from the back so that the knot stays on the outside of the sensor. Now stitch your stitches but there is no need to go all the way through the neoprene so that they are visible and vulnerable on the outside. You can dive into the neoprene and at the same time this isolates the conductive thread. When you have finished you stitches you will want to bring the thread to the patch of conductive fabric that is fused to the tab. If you plan ahead you can aim to end close by. With about 5 to 7 stitches attach the conductive thread to this patch and then cut it.
Do the same on the other side of neoprene.
