I stock a range of Copper & Aluminium foils for such uses in card making and embossing.
I have coil suitable for DIY solar panels, please contact me for details.
I am now stocking Aluminium suitable for making Marquee Letters. These are available in 6″ & 8″ widths and cut to customers length requirements.
If you require a wider or narrower width, I am able to provide that also.
