Homebrew PCBs

I recall DJ Delorie makes a "pocket" out of the 2 sides of artwork, aligned
by holding the sides up to a strong light, securing them together, and then
inserts the PCB. It wouldn't be milli-inch-accurate, but it's top of my
"I'll try that if I ever need a 2-sided board" list.

I did get a small board lined up well enough for a 2-sided iPod connector
(0.4mm) to work using some diagonally-opposite pinholes.
