Homebrew PCBs

Guess someone has already done that: at least one guy on a DIY audio group
here in Brazil used to do some simpler boards by masking with plotter cut
vinyl, the same used on sign making. The trace width was large, as well as
spacing, and the board was single sided, but for simpler projects it should
work.
