This conductive fiber is super interesting! It's great for felting and could also be spun into yarn if that's your thing. We tested many different fiber thicknesses for needle felting and found that this one (20um fiber thickness) is the most pleasurable to work with. Use about 0.2g of the stuff to make a felt touch button suitable for use for a capacitive touch sensing circuit. Make felt controllers or felt buttons onto an existing wool sweater!
