Congrats on progress. It is very satisfying to see that pattern come
out on the copper.
You really dont need to use PnP. Try, instead, using a decent
quality inkjet paper (not glossy, no special coatings, ...). Use a
very hot iron (cotton, highest setting) and lots of pressure. I use
kids construction paper between the iron and the transfer paper to
even out the irregularities. Once you are done with the ironing,
turn off the iron but leave it sitting on the board/paper until it
cools down a bit (below the fusing point) to ensure good toner
adhesion to the copper. this process is highly reliable for me and
the last few boards I did required NO touching up.
