Update on previous post: Parchment paper does NOT give good coverage on large areas like ground planes. I did a couple more boards this morning and the ground planes still did not have good coverage. As a control I used a piece of Pulsar paper with the same layout, same printer settings, same laminator temperature setting, even cut both PCB from same sheet to be sure everything was as close to same as possible.
The Pulsar paper gave GOOD solid black ground planes where the parchment paper ground planes were spottie with too much copper showing thru. No point in etching, I can tell it would not "look" good. It would still work and make a very usable board.
Maybe the parchment paper would be to do a component transfer over the etched board for have a component layout?
Osgeld and others - please post your results.
