now, they have a silver ink that you can use to 'draw' a pcb on just
about any surface.

That kind of product has been around for several decades, it works OK
for repairing damage runs, not so good for power runs.

Never take life seriously. Nobody gets out alive anyway.

Get down to your stained glass hobby store. You can buy 1, 2 and 4 ounce copper tape with a pretty tenacious adhesive on the back. Normally used for edging bits of glass before soldering them into a unit.

The widths range from.050" to about 3/4" so you can do power busses, simple 'wire' runs, ground areas, etc. (Also add ground areas to existing boards as needed.) The silver ink pens are great to connect to and among fine pitch and SMD parts. Regrettably, it takes a steadier hand than mine is these days. :)

Hobby Lobby also has 12" wide rolls that are inexpensive, those are
good to tape on the inside of plastic boxes to provide a measure of
electrostatic shielding.
