Ben there done that, BACK IN THE MID-70s. My gosh, am I that old.

Anyway, from what I remember that was a pain.

1) Make the PCB artwork.
2) Print it on paper.
3) Expose the negative.
4) Develop the negative.
5) Place the negative on a photo sensetive PCB, glass on top of that 
with a weight to make the negative in direct contact with the PCB. 
This has to be done under darkroom lighting.
6) Expose the PCB to the UV.
7) Develope the PCB.
8) Etch the PCB.
9) Cut to size and drill.

I realize some of these steps are done in the Toner-Transfer method. 
The TT method must be reconized as a homebrew method.

You are doing this the Twenty-first century way and I for sure don't 
know what might be considered the best homebrew way of doing. I would 
like to get back into making my own prototype PCBs. I'm sure you are 
using one of the better methods. How is the best for me to start 
making PCBs?

Thanks,
Mike
