you can
accomplish rudimentary masking and etching by using cheap
packing tape. Encapsulate the board then slice and remove portions of
the board you'd like to etch away. No copper sulfate IIRC (the
etchant) won't eat your fingers. Just DON'T pour it down the drain,
protect your clothes and be careful of animals.
I've never heard of anyone using copper sulfate as an echant--I don't
even see how it would work, chemically. Heck, I spray the stuff on my
fruit trees during the wintertime.
