I made my own a few days ago but i had a custom glass made that is white coated on top later but very smooth and finger friendly so you dont get sticky fingers plus reflection free.

@jojojojoeable Yes you should use Xylol or similar material. I don't know exactly why you need to use that material, probably breaks down the silicon into a liquid to make it easier to apply to your touch surface.

Hi. Thanks for your reply. I'm gonna put this touch panel in to our school festival. But it still does not working. Can you tell me more about sylicone? Why xylophone is needed?

@victom111 I don't sell the ribbon shorter than the 5 meter reels (500cm). Please see my supplier Environmentallights for cut-to-length orders. You do save a lot of money by buying a full reel though consider that.
