Yeeha!
Etched my first board today and it looks great so far! I haven't
drilled it yet, but I'm very happy with it.

Details:
Samsung scx-4100 printer
glossy magazine paper
soapy water & kitchen scrubby wash, dry, bathroom cleaner, wash,
dry, flash free solvent/degreaser
clothes iron at hottest setting
5-7 minutes ironing
cool
soak in warm soapy water
gently remove paper
gentle toothbrush rub
sharpie touch up
HCl and H202 etchant in plastic tofu container (outside)

I got some 1oz. CEM boards from Bill at abcfab. I can highly
reccomend him.

When the etchant is no longer active is it safe to dispose of on the
ground outside? I'm assuming that the copper in it will kill any
plants, but does the acid need to be neutralized any further? Add
some CaCO3?

Thanks,
Chester
