Homebrew PCBs

Having problem with sharpie pens, the ink is lifting off in places,
and sometimes even flotas away in the shape it was!

Its odd looking at a hols and a short trace washing round in your
etchant, like a tadpole........

Do some colors really work better than others, I can only get blue at
the moment.

Do some other pens work better?
