Homebrew PCBs

I have to go over the sharpie spot two or three times to get good coverage.  The first "marking" will not be totally dark, but by the 3 or 4th time marking over the same spot it seems to work pretty good.  I've used both the fine point and Ultra fine point - the fine point is NOT what I would consider a fine point, more of a blunt point - 30 mil would be with a new sharp "fine" point.
