Homebrew PCBs

On a different subject entirely,

I am 100% happy with press-n-peel  but there again I don't have to do 
any super fine work. I gave up UV exposure several years ago except 
for etching on curved aluminium castings.

I keep looking at the picture on the group homepage and wince at the 
amount of etchant used to etch those big empty areas....  :-(

I know 99% of the group will already be filling those areas with 
copper, but in case there are any beginners out there, unless there is 
a good reason to remove the big areasof copper,  (like RF work) it is 
more economical to leave as much copper on the board as possible.
