Homebrew PCBs

I usually drill a few holes before etching to allow getting the backside lined up good (on double sided boards), then drill all the other thru holes after etching.  I leave a small "etched" space in the center of each pad that will have a hole drilled - this seems to help center the drill point for drilling.
