Machine-sewing solderable circuits

Using Karl Grimm’s copper thread to sew solderable circuit traces to fabric. Karl Grimm’s copper thread is very much like wire, but much more flexible and it doesn’t quite look like wire. I haven’t had much luck using it as the bobbin thread in my sewing machine, but you can sew in place using regular thread to sew a zigzag stitch on top of it.
