I would like to try making a small quantity of photo-etched PC boards
for experimentation purposes.  I entered a small schematic using the
PADS-LOGIC software, and did a layout using PADS-PCB.  I have two
questions:

1) Can I realistically make double sided PC boards?  My first board will be
   single-sided, but I would like to try more complicated boards later.

2) What are the best photo-resist methods and chemicals?  I have seen ads for
   both positive and negative photo resist.  Is there any difference other than
   the need for negative vs. positive artwork?

Any recommendations on etching suppliers would be appreciated, also.

I'll summarize responses to the net.  Maybe this would make a good start
for an FAQ...

Thanks!
