Homebrew PCBs

I'm honestly not sure what the thickness of the board was - I don't still
have the packaging, but I know that the subsequent board I etched in an
etching container was from the same batch.

Also, I used the same bottle of FeCl in both situations.

I suspect I might get better results by heating the etching before sponging,
but most of the howtos I've read indicate that that's not necessary.

Maybe I wasn't using enough pressure?  I was trying to be careful to
maintain my Sharpie traces, but now I know that those are a lost cause, and
the toner isn't going anywhere, so I don't need to be so worried about
applying too much pressure.

I'm certain I could probably make the system work with some experimenting,
and I'd be happy to discuss the process I used with anyone who's trying to
troubleshoot where it went wrong.  But since it's supposed to be a
convenience shortcut, I'm not personally going to be pursuing it much
further when I already have something that "works for me".
