Finally got around to etching those circuits yesterday.  The PNP-Blue
stuff is amazing!  I got 100% perfect results on my second try.

On my first try, of course, I did a number of things wrong: I didn't scrub
all of the oxide off of the copperplate, so the PNP-blue did not entirely
adhere.  Additionally, I 'overcooked' the PNPblue material, skortching it
and making it flake off in places.  (but my shirts are all well-pressed) 

On my second try, I read the directions ... duh!  :)

Just adding my voice to the static,
Jonathan.
